1. Cisco Trunk Interface and Native VLAN
When a Cisco switch is configured as a trunk interface, by default, traffic becoming to the native
VLAN (VLAN 1) is not trunk encapsulated. Cisco uses the native VLAN for such proprietary
protocols such as CDP, PAgP, and VTP. To tag the native VLAN, the Cisco global vlan dot1q tag
native command must be used where, unless you change the native VLAN identifier at an
interface level, VLAN 1 will be tagged. At an interface level, the switchport trunk native vlan <14094> command can be used to change the VLAN identifier of the native VLAN. For example, the
following configuration enables native VLAN tagging using VLAN 1050 as the native VLAN on
port 1/0/18 on a Cisco 3750.
!

switchport mode trunk

mls qos trust dscp
!
If you have an older Cisco switch that does not support native VLAN tagging and you need to
pass the native VLAN traffic via an Avaya switched network, the Avaya switch can be configured
to support an untagged default VLAN. Although Avaya also uses VLAN 1 as the default VLAN,
any VLAN number can be used as the default VLAN. The following shows a configuration
example for both an ERS8600 and an ERS5000 switch using VLAN 1050 as the default untagged
VLAN.

3. Cisco EtherChannel to Avaya Switch
Cluster
For this configuration example, a Cisco 3750 switch is used at the SMLT access layer using
EtherChannel to connect to the ERS8600 Switch Cluster. Note that any local proprietary loadbalance mechanism or 802.3ad can be used to connect to a Switch Cluster. Overall, we will
configure the following items:
•
IST using MLT 1 with port members 2/1 and 3/1 and IP subnet 10.1.2.0/30
•
SLT 129 for the Cisco 3750 Edge switch with VLAN 3
•
Enable EtherChannel on the Cisco 3750 with tagged port members 1/0/23 and 1/0/24
It is recommended to use the same MLT ID’s between the two SMLT clusters for ease
in configuration and trouble-shooting.
It is recommended to use a unique IP subnet between the SMLT Cluster.
L
April 2010
Well, if you need an OSPF adjacency between the IST peers, you have to create a
separate IP subnet on the IST, since we do not recommend enabling routing protocols
over the IST IP
As illustrated in the diagram above, the SMLT or SLT ID is local to an SMLT Cluster.
The ERS8600 support up to 128 SMLT ID’s using ID’s 1 to 128. The SLT ID’s can be
any value from 1 to 512, however, it is recommended to use a SLT ID greater than the
maximum possible SMLT ID so as to not use up a possible SMLT instance. Hence the
reason we are using SLT-129 in Switch Cluster. Please note that this is not a
requirement; it just illustrates the flexibility of the solution. Also note that the SMLT ID or
SLT ID used on each peer in the Switch Cluster must be the same.

3.1.1.7
SLPP
For this example, we will pick ERS8600-1 as the primary switch for the switch cluster. SLPP will
be enabled globally and on the SLT access port 4/6 on the switch cluster. On the SLT primary
switch, we will set the SLPP packet-rx-threshold to 5 while on the SLT secondary switch, we will
set the SLPP packet-rx-threshold to 50 for the access ports.

SLPP should only be enabled on the SMLT access or core ports and not on the IST port
members.
ERS8600-1: Step 1 – Enable SLPP and in regards to the core port on the primary switch
only, set the SLPP Rx-Threshold with a value of 5

3.1.2.1
Spanning Tree, PVST+, is enabled by default on a Cisco switch. Spanning Tree should
be left enabled on all user ports and set for portfast, but disabled on the trunk
EtherChannel ports. This can be accomplished on the Port-channel ports using the
command ‘spanning-tree bpdufilter enable’ command.
The EtherChannel load balance method can be changed from the default setting by
using the command port-channel load-balance <dst-ip|dist-mac|src-dst-ip|src-dstmac|src-ip|src-mac>.

If the EtherChannel is not coming up and you notice the Interface line protocol is down
by using the show interfaces gigabitEthernet <port>, check to see if auto trunk
encapsulation is enabled by issuing the command show etherchannel detail.
For example:
Problem: Interface line protocol is down
C3750-2#show interfaces gigabitEthernet 1/0/24
GigabitEthernet1/0/24 is up, line protocol is down (suspended)
Entering the following command to look at the EtherChannel details:
L
C3750-2# show etherchannel detail

Probable reason: trunk encap of Gi1/0/24 is auto, Po1 is dot1q
Port-channels in the group:
--------------------------This tells us we should disable auto trunk encapsulation on this interface
To fix this problem, enter the following commands:
C3750-2(config)#interface range gigabitEthernet 1/0/23 - 24
C3750-2(config-if-range)#switchport trunk encapsulation dot1q
C3750-2(config-if-range)#do show int gig 1/0/23
GigabitEthernet1/0/23 is up, line protocol is up (connected)

4. LACP Interoperability between a
ERS8600 Switch Cluster and Cisco 3750
For this example, we will configure the following:
•
A Link Aggregation Group (LAG) is configured between the ERS8600 triangle topology
and a Cisco 3750.
o
VLANs 10 and 20 will be tagged across the LAG
o
LACP key = 4
o
MLT ID = 4
o
SMLT ID = 4
o
LACP Timeout = Long
•
Use MLT 1, VLAN 2 for the IST with port members 1/1 and 2/1 using IP Subnet
10.1.2.0/30
•
For this application to work, we will need to configure the SMLT System Identifier so that
LACP global identifier is the same on both ERS8600-1 and ERS8600-2. Although you
can use any MAC address, we will simple use the LACP identifier from ERS8600-1 to
avoid any possible duplicate addresses.
L
Please note that Cisco does not support LACP short timer
L
Please note that in order for LACP to work all links must be operating at the same
speed. If LACP does not come up, please check that the interfaces on both ERS8600
switches in the Switch Cluster are operating at the same speed. For example, if port
3/23 on ERS8600-1 is using a legacy module 8648TX and port 3/23 on ERS8600-2 is
using an R-module 8648GTR, by default port 1/23 on ERS8600-1 will connect at
100Mbps and port 3/23 on ERS8600-2 will connect at 1000Mbps. To solve this issue,
either set the speed to a fixed rate or set the auto-negotiation advertisements.

4.1.1.9
SLPP
SLPP will be enabled globally and only on the SMLT access port 3/23 for VLAN 10 and 20. On
the SMLT primary switch we will set the SLPP packet-rx-threshold to 5, while on the SMLT
secondary switch we will set the SLPP packet-rx-threshold to 50. For this example, we will pick
ERS8600-1 as the primary switch.
L
The recommended SLPP receive threshold value for the primary switch is 5 and 50 for
the secondary switch in an SMLT cluster.

SLPP should only be enabled on the SMLT access ports and not on the IST port
members.
ERS8600-1: Step 1 – Enable SLPP
ERS8600-1# config slpp add 10,20
ERS8600-1# config slpp operation enable
ERS8600-1# config ethernet 3/23 slpp packet-rx-threshold 5

4.1.1.10 Ext-CP Limit
Enable Extended CP-Limit globally with trap set to normal. Also enable Extended CP-Limit with
SoftDown option on port 3/23. Since the port is a 100Mbps Ethernet interface, we will set the
threshold to 80%.
ERS8600-1: Step 1 – Enable EXT-CP-Limit

In order for LACP to come up between an Avaya and Cisco switch, Cisco DTP
(Dynamic Trunking Protocol) and native VLAN encapsulation should be disabled. Use
the show interface gigibitEthernet <port number> switchport command to verify if DTP is
enabled or not. If it is, enter the command switchport nonegotiate command at the portchannel and interface level. Also, disable tagging of the native VLAN (VLAN 1 by
default) by issuing the CLI command no vlan dot1q tag native. In addition, the Cisco
switch VTP (VLAN Trunking Protocol) should be set for transparent and CDP (Cisco
Discovery Protocol) should be disabled.

On ERS8600-2 in the switch cluster verify the following information:
Option
Verify
SystemId
In an SMLT configuration, both switches in an SMLT cluster must use
the same System ID. You can use the System ID from either switch.
This is to ensure proper LACP operation at the edge switch in case of a
SMLT cluster switch failure. This will ensure the edge always sees the
same ID from the LACP packets from both switch in the cluster in case
if one of the switches should fail
SYS ID
For this example, the value of 00:01:81:28:84:00 should be displayed
when using the LACP actor-admin command via either switch in the
SMLT cluster and also via the Cisco switch.
The LACP partner value will be the value send by the Cisco switch and
verified by using the command “show lacp sys-id’ on the C3750. For
this example, the value is 00:0d:65:cc:09:00.

Avaya and Cisco
Cisco supports three Spanning Tree modes of operation, PVST+, Rapid-PVST, and MST. Of the
three, only MST support standards based 802.1s which can interoperate with any of Avaya
switches offered today. In regards to the ERS8600 only, it also supports the older PVST+
Spanning Tree mode of operation.
By default, Cisco comes enabled with Rapid-PVST. This proprietary protocol combines the
functionality of RSTP with PVST creating an RSTP (802.1w) instance per VLAN. The Cisco
implementation also defines a concept of “native” VLAN whereby BPDUs generated for the native
vlan are standard compliant (802.1w for Rapid-PVST) whereas BPDUs generated for all other
VLANs are modified with a Cisco multicast MAC address and are q-tagged with the vlan-id they
belong to, thus rendering them incompatible with the standard.
It is therefore highly recommended to avoid Cisco’s proprietary Rapid-PVST and enable instead
MST on Cisco and MSTP on the Avaya switches.
It is still possible to make the Rapid-PVST protocol interoperate with Avaya standards based
802.1w (RSTP) by letting Cisco’s native VLAN instance interoperate with Avaya single RSTP
instance and allowing the other Cisco Spanning Tree instances to be flooded transparently
across the Avaya switches. The native VLAN by default is set to VLAN 1. This method will work
providing the native RSTP instance on an Avaya switch never blocks any interface. Hence, it can
get a little difficult setting up a network.
If the Avaya switches are being deployed as edge switches onto a Cisco Core using Rapid-PVST
an even better approach is to simply disable Spanning Tree on the Avaya switch uplink ports to
the Cisco core and let the Cisco core take care of any loops. This is illustrated in Figure 2. The
proprietary BPDUs generated by the Cisco Core will simply be re-flooded in the vlan by the Avaya
edge switch and thus one of the Cisco’s will block one of the uplinks. Note that in this design only
non-native VLANs must be tagged on the uplinks to the Avaya switches. The native VLAN on the
Cisco Core needs to be set to some unused vlan; for instance left configured at default VLAN 1
which should never be used.

5.1 Cisco PVST+ to Avaya Switch Cluster
Configuration Example
For this configuration example, two Cisco 3650 switches are used at the access layer and
configured with PVST+ to connect to an ERS8600 Switch Cluster. The Cisco Switches could be
seen as the Distribution Layer of a large Network or just as a couple of cascaded switches at the
edge of a network where configuring Etherchannel is not possible because of the Cascade
implementation.
This type of configuration is useful when transitioning from a Spanning Tree Solution (older L2
deployments) to an Avaya Switch Cluster Solution.
At this particular point in time, there is no elegant way to implement any flavor of Spanning Tree
across a Switch Cluster Core. By design, the IST in a switch Cluster does not allow BPDU
packets between the core switches.
In this particular configuration, we take advantage of the fact that PVST+ BPDUs are used in
every VLAN except for the Default VLAN. PVST+ BPDUs uses a L2 Multicast Destination
Address (01:00:0C:CC:CC:CD) which in turn make things simple when leaving via a tagged
interface (802.1q) as the BPDUs are tagged with their corresponding VLAN ID.
The individual switches of an Avaya Switch Cluster do not recognize these Multicast addresses
as BPDUs so they just flood these multicast frames on their appropriate VLANs (even across the
IST).
This means that the Avaya Switch Cluster is completely transparent to PVST+ and the two Cisco
Switches will go through their normal Spanning tree process of preventing a loop by eventually
blocking a link. Depending on PVST+ configuration of the Cisco Switches, the blocked link will
either be the link between the 2 Cisco Switches (as shown in the diagram) or one of the CiscoAvaya links.
The configuration is very simple especially when considering that PVST+ is the default on Cisco
Switches.
Note that in this scenario, the Avaya Switch Cluster is transparently passing the PVST+ BPDUs
across the IST therefore allowing the Cisco Switches to detect a loop and eventually preventing
any problem arising from such a loop by blocking a port on the specific VLAN. The Switch Cluster
is not participating in any way to Spanning tree and therefore could never become a root bridge
or ever block a link to prevent a loop from occurring nor will it fast age MAC addresses following a
PVST+ active topology change.

In summary, we will configure the following:
•
IST configured as normal using VLAN 2, MLT 1 with port members 2/1 and 3/1, and IP
subnet 10.1.2.0/30
•
Three VLANs will be configured with management VLAN 5 and VLANs 10 and 20 for end
user access
•
Since the Cisco switches will be using PVST+ to manage the dual homing to the Avaya
Core, the Switch Cluster will not need to have a SMLT or an SLT link setup for the Cisco
Switches. The only requirement is to have the correct VLANs set on the individual ports
on each Core switch and for the VLAN to be crossing the IST of course.
•
It will be possible of course to setup SMLT/SLT to other distributions or edges that
support link Aggregation back to our switch Cluster.
1
The use of the default VLAN (VLAN 1) is not recommended in most cases, but in this
particular scenario even more so. Even in PVST+ mode, the Default VLAN always
sends its BPDUs to the IEEE STP MAC address (0180.c200.0000) in untagged frames.
This could vary from inconvenient, when the BPDUs are dropped by the receiving port
on the Switch Cluster, to potentially dangerous as there could be no way of detecting a
loop on the Default VLAN. For that reason alone, the Default VLAN should not be used
in this scenario.
In addition, it is also recommended not to use the Native VLAN setting on trunk ports
used to interconnect to a Switch Cluster. The Native VLAN on a Trunk port (802.1Q)
would be sent out as untagged frames and, according to Cisco documentation, the
native VLAN would also send out BPDUs to the IEEE STP MAC address
(0180.c200.0000) in untagged frames.
To keep things simple, do not use the Default VLAN (VLAN 1) and do not use the Native
Vlan option on the trunk ports connecting to the Switch Cluster.

To be extra safe, we will configure SLPP on the ports connecting to the Cisco Switches on the
VLANs used on the Cisco Switches. This is to make sure that if a configuration error occurs on
the Cisco Switches, the Avaya Switch Cluster will still be able to detect and prevent a loop from
occurring
For this example, we will select ERS8600-1 as the primary switch for the switch cluster. SLPP will
be enabled globally and on the ports used to connect to the Cisco Switches. On the primary
switch, we will set the SLPP packet-rx-threshold to 5 while on the secondary switch; we will set
the SLPP packet-rx-threshold to 50.

MSTP Configuration Example – One Region
For this configuration example, we will configure the following:
•
•
•
•
•
•
•
•
•
•
•
April 2010
All switches are configured in the same region named region1 and using revision 1
C3750-1 will be configured so that it will become the CIST Root by configuring the lowest
CIST Priority of 4096.
C3750-2 will be configured so that it will become the CIST backup by configuring the next
highest CIST Priority of 8192.
Three VLANs will be configured, VLAN 200 for management and VLANs 1000 and 1100
for end user access
For the management VLAN 200, we will configure a management IP address as shown in
the diagram above – for this example, no routes are configured for the management as it
is a simple Layer 2 network
We will configure two MSTI instances; MSTI 1 for VLAN 200 and 1000, and MSTI 2 for
VLAN 1100 to load balance traffic as illustrated in the diagram above
C3750-1 will be configured as the root bridge for MSTI 1 and backup root for MSTI 2
C3750-2 will be configured as the root bridge for MSTI 2 and backup root for MSTI 1
8600-1 will be configured with a CIST and MSTI 1 priority of 12288 so that will become
both CIST and MSTI 1 root if both C3750-1 and C3750-2 should fail
8600-2 will be configured with a CIST priority of 16384 so that it will become CIST root if
C3750-1, C3750-2, and 8600-1 should fail
8600-2 will be configured with a MSTI 2 priority of 12288 so that it will become MSTI 2
root if both C3750-1 and C3750-2 should fail

On the ERS4500, if a port is removed from the default VLAN (VLAN 1) prior to adding
the port as a port member to a different VLAN, STP participation is disabled for this port.
Hence, at an interface level, Spanning Tree Port must be re-enabled for each removed
port. This inconvenience can be avoided if the port or ports are removed from the
default VLAN after the port or ports are added to a different VLAN.

5.3 MSTP Configuration Example - Two Regions
In this configuration example, we take the exact same configuration used in Section 3 with the
exception of creating a second region with switches 8600-1, 8600-2, 4550T-1, and 4548GT-2. All
the same CIST and MSTI priorities will be used. The only configuration change will be the MSTP
region name as illustrated in the diagram above. This will result in only one forwarding port
between the two regions via 8600-1 port 1/23. In the region named “region2”, 8600-1 will become
the root bridge for MSTI 1 while 8600-2 will become the root bridge for MSTI 2. 8600-1 will also
become the CIST Regional Root for the region named “region2” based on the priority settings
configured.

6. OSPF MD5 Authentication
For this example, we will configure the following:
•
MD5 OSPF authentication between an Avaya ERS8600 switch and a Cisco 3750 switch
•
We will set the MD5 password to avayatocisco
1
Note that Cisco will send OSPF hello messages with LLS (Link-Local Signaling). The
Avaya ERS8600 does not accept LLS and thus will never form an OSPF neighbor if LLS
is left enabled.
6.1 Configuration Steps
6.1.1 Enable MD5
ERS8600-1: Step 1 – Add and enable MD5 message key

7. Avaya IP Phone to Cisco Switch
The following configuration example covers various methods for configuring a Cisco 3750 to
support both voice and data on the same port with an Avaya IP Phone.
The access ports will be configured to allow untagged data traffic and tagged voice traffic using
VLAN 1000 for the Data VLAN and VLAN 600 for the Voice VLAN. The Avaya IP Phone can
either use double DHCP to get the Voice VLAN ID from a DHCP request on the data VLAN or the
Cisco 3750 switch could be configured for LLDP-MED to tell the Avaya IP Phone what the voice
VLAN ID is.
For QoS, the Cisco 3750 can either be configured to trust the layer 2 p-bit value or layer 3 DSCP
value. At a layer 2 level, the switch can be setup to only trust only the tagged voice VLAN 802.1p
value and remark all untagged traffic with a DSCP value of 0. At a layer 3 level, the switch can be
configured to trust the DSCP values from both the voice and data VLANs without a policy-map
configured, or only trust the DSCP value from the voice VLAN and remark the data VLAN with a
policy-map defined.
7.1 Config Steps
For this configuration example, we will assume an Avaya model 1230 IP Phone.
7.1.1 PoE
By default, on a Cisco 3750, the switch automatically detects and supplies power if the connected
device requires it. If you wish, use the following interface commands to set the desired PoE
settings:
interface gigabitEthernet <interface number>
power inline auto (default setting and preferred for Avaya IP Phones)
power inline auto max <4000-15400> milli-watts (To limit the power in auto mode)
power inline static (To turn on power to the port even if there is no PoE device
detected)
power inline static max <4000-15400> milli-watts (To limit the power in static mode)
power inline never (To turn off power to the port)
April 2010
Avaya / Cisco Interoperability
Technical Configuration Guide
80
avaya.com
power inline consumption <4000-15400> milli-watts (To set the amount of power
consumption)
7.1.2 Avaya IP Phone default DSCP values when used with a Cisco Switch
The Avaya IP Phones uses a p-bit value of 6 and DSCP value of 46 for Voice Media. For Voice
Signaling, the Avaya IP Phone uses a p-bit value of 5 and DSCP value of 40. The following
command displays the default DSCP mappings on a Cisco switch.
C3750-2#show mls qos maps cos-dscp
Cos-dscp map:
cos:
0 1 2 3 4 5 6 7
-------------------------------dscp:
0 8 16 24 32 40 48 56
In order to support Avaya IP Phones on the Cisco switch, we need to change CoS value 6 with a
DSCP value of 46. The can be accomplished by using issuing the following commands:
C3750-2(config)#mls qos map cos-dscp 0 8 16 24 32 40 46 56
C3750-2(config)#mls qos (enter this command to enable QoS)
C3750-2(config)#do show mls qos maps cos-dscp
Cos-dscp map:
cos:
0 1 2 3 4 5 6 7
-------------------------------dscp:
0 8 16 24 32 40 46 56
7.1.3 QoS at Layer 2 Option
If we configure the Cisco switch, as in this example, to support untagged data traffic and tagged
voice traffic, the switch can be setup to trust only the 802.1p (p-bit) values from the tagged voice
VLAN. All untagged traffic will be remarked with a DSCP value of 0. This can be accomplished
with the mls qos trust cos interface level command.
Overall, the configuration should look like the configuration shown below to trust only the p-bit
values from the tagged voice VLAN. We will also change the cos-dscp 6 value from the default
DSCP value of 48 to a DSCP value of 46.

If you wish, you can also add a default CoS value for the untagged data VLAN traffic. By default,
all the data traffic is remarked with a DSCP value of 0. If you set the mls qos cos <0-7> on a
port, the switch will set the CoS value of all frames from the untagged data VLAN to the
configured CoS value. The following shows a configuration changing default CoS value of 0 to 2
which in turn will remark all the untagged data traffic with a DSCP value of 16.

7.1.4 QoS at Layer 3 Option
The following is a configuration example of configuring the Cisco switch to trust the DSCP value
instead of the p-bit value. Please see Section 7.1.2 regarding changing the default CoS mappings
to support Avaya IP phone.

The above configuration will trust all traffic both from the untagged data VLAN and the tagged
voice VLAN. In some cases, you may not want to trust the data VLAN. If this is the case, a policymap can be created to pass the voice VLAN traffic as-is and remark the data VLAN traffic.
Assuming the data VLAN uses a subnet of 192.168.100.0/24 and the voice VLAN uses a subnet
of 192.168.60.0/24, the following configuration will pass the CoS traffic from the voice VLAN as-is
and remark the data VLAN traffic to a DSCP value of AF11.

7.1.5 LLDP-MED
To enable LLDP-MED, you simple have to enter the command lldp run. The interface level

8.2 Cisco Phone Configuration
The Cisco phone used for this example is based on software version SCCP41.8-3-4SR1S in
SCCP mode. A remote Cisco call server (CUCM) was set up to recognize and register the phone
when contacted.
Note that the Cisco phone is required to support LLDP-MED in order to inter-operate with the
ERS 4500. Support for LLDP-MED was introduced in release 8.3(3) on most, but not all, phone
models. Please consult release notes.
C7961G Step 1 – Confirm the Cisco phone supports LLDP-MED
•
Press the “Settings” button
•
Select “3 – Device Configuration”
•
Select “9 – Network Configuration”
•
Ensure that “LLDP: PC Port” is set to “Enabled”
•
Ensure that “LLDP-MED: SW Port” is set to “Enabled”
•
Press “Exit” twice to return to the main “Settings” menu.
C7961G Step 2 – Confirm that the Voice VLAN Id is not statically configured and
DHCP is enabled
April 2010
•
Select “2 – Network Configuration”
•
Verify that the parameter “21 - Admin. VLAN Id” is set to a null value
(i.e. should be blank, no value). The Voice VLAN Id should not be
statically configured because it will be advertised by the ERS 4500 via
LLDP-MED. If this needs to be changed press “**#” to unlock the
configuration and make the change.
•
Verify that “22 – DHCP” is set to “Yes”
•
Press “Exit” twice to exit the “Settings” menu.

8.3.3 Verify Cisco Phone operations
Once the phone learns the Voice VLAN via LLDP-MED it sends a DHCP Discovery/Request.
The DHCP Server returned an IP address, default gateway, DNS Server, DNS Domain Name,
and DHCP option 150 – “TFTP Server IP Address” so that the phone can reach its Call Server.
Note that there are multiple methods in which the Cisco phone can learn of its Call Server:
•
Static IP address
•
Option 150 (single IP address)
•
Option 66 (first IP address or Domain Name System [DNS] name)
•
Lookup CiscoCM1.your.domain
To verify that the Cisco phone learned the Voice VLAN:
April 2010
•
Press the “Settings” button
•
Select “2 – Network Configuration”
•
Verify that the parameter “20 – Operational VLAN Id” is set to the Voice VLAN Id.

Add Route Policy to Re-distribute VRF BGP Routes into the VRF OSPF Instance
All external routes learned by IP-VPN will be distributed by BGP. In order for the CE routers to
learn these routes, we must configure each VRF as and OSPF ASBR and enable route redistribution.

is operational, c) ensure that you have PE-PE connectivity by performing an ‘mplsping’
to the remote PE CLIP address and d) ensure that you ping the VRF interfaces.
For example, in reference to PE-1, ensure that it can ping PE routers PE-1 and PE-2 as
follows using CLIP/Loopback addresses:

Step 1b – Enter the following command to display the MPLS out label pushed out, for this
example, by PE-1. FTN refers to the FEC (Forwarding Equivalence Class) to HHLFE (Next
Hop Label Forwarding Entry).
ERS8600-1:5# show mpls ftn info
NNCLI command: ERS8600:5# show mpls ftn
Result:

Out Label : 100032 ; Out Port : Vlan 2015 ; Next-Hop : 10.93.102.1
Type : ldp-dynamic
Step 2 – Use the following command to specify a specific path, for example, to PE-2 Circuitless
IP address

Out Label : 100032 ; Out Port : Vlan 2015 ; Next-Hop : 10.93.102.1
Type : ldp-dynamic
Step 3 – To test if the MPLS path is operation, i.e. to 10.100.100.4/32, enter the following
command
ERS8600-1:5# mplsping ipv4 10.100.100.4/32 count 3
NNCLI: ERS8600:5#ping-mpls ipv4 10.100.100.4/32 count 3

Success for FEC 10.100.100.4/32: mpls_seq=2.
Success for FEC 10.100.100.4/32: mpls_seq=3.
