This section explains how to set the related parameters for cellular network. The UR52/UR55 cellular
router has two cellular interfaces, namely SIM1 and SIM2. Only one cellular interface is active at one time.
If both cellular interfaces are enabled, then SIM1 interface takes precedence by default.
A typical use case would be to have SIM1 configured as the primary cellular interface and SIM2 as a
backup. If the UR52/UR55 cannot connect to the network via SIM1, it will automatically fail over to SIM2.

4.2.1.7 Loopback
Loopback interface is used for replacing router's ID as long as it is activated. When the interface is DOWN,
the ID of the router has to be selected again which leads to long convergence time of OSPF. Therefore,
Loopback interface is generally recommended as the ID of the router.
Loopback interface is a logic and virtual interface on router. Under default conditions, there's no loopback
interface on router, but it can be created as required.

4.2.2 Firewall
This section describes how to set the firewall parameters, including ACL, DMZ, Port Mapping and MAC
Binding.
The firewall implements corresponding control of data flow at entry direction (from Internet to local area
network) and exit direction (from local area network to Internet) according to the content features of
packets, such as protocol style, source/destination IP address, etc. It ensures that the router operate in a
safe environment and host in local area network.
4.2.2.1 ACL
Access control list, also called ACL, implements permission or prohibition of access for specified network
traffic (such as the source IP address) by configuring a series of matching rules so as to filter the network
interface traffic. When router receives packet, the field will be analyzed according to the ACL rule applied
to the current interface. After the special packet is identified, the permission or prohibition of
corresponding packet will be implemented according to preset strategy.
The data package matching rules defined by ACL can also be used by other functions requiring flow
distinction.

UR52 & UR55 User Guide
Linkage between Track Module and SLA module
Once you complete the configuration, the linkage relationship between Track module and SLA module will
be established. SLA module is used for detection of link status, network performance and notification of
Track module. The detection results help track status change timely.
- For successful detection, the corresponding track item is Positive.
- For failed detection, the corresponding track item is Negative.
Linkage between Track Module and Application Module
After configuration, the linkage relationship between Track module and application module will be
established. When any change occurs in track item, a notification that requires corresponding treatment
will be sent to Application module.
Currently, the application modules like VRRP, WAN failover and static routing can get linkage with track
module.
If it sends an instant notification to Application module, the communication may be interrupted in some
circumstances due to routing's failure like timely restoration or other reasons. Therefore, user can set up a

4.2.6.3 VRRP
The Virtual Router Redundancy Protocol (VRRP) is a computer networking protocol that provides
automatic assignment of available Internet Protocol (IP) routers for participating hosts. This increases the
availability and reliability of routing paths via automatic default gateway selections in an IP sub-network.
Increasing the number of exit gateway is a common method for improving system reliability. VRRP adds a
group of routers that undertake gateway function into a backup group so as to form a virtual router. The
election mechanism of VRRP will decide which router undertakes the forwarding task, and the host in LAN
is only required to configure the default gateway for the virtual router.
In VRRP, routers need to be aware of failures in the virtual master router. To achieve this, the virtual
master router sends out multicast “alive” announcements to the virtual backup routers in the same VRRP
group.
The VRRP router who has the highest number will become the virtual master router. The VRRP router
number ranges from 1 to 255 and usually we use 255 for the highest priority and 100 for backup.
If the current virtual master router receives an announcement from a group member (Router ID) with a
higher priority, then the latter will pre-empt and become the virtual master router.
VRRP has the following characteristics:
- The virtual router with an IP address is known as the Virtual IP address. For the host in LAN, it is only
required to know the IP address of virtual router, and set it as the address of the next hop of the
default route.
- The network Host communicates with the external network through this virtual router.
-
A router will be selected from the set of routers based on its priority to undertake the gateway
function. Other routers will be used as backup routers to perform the duties of gateway for the
gateway router in the case of any malfunction, so as to guarantee uninterrupted communication
between the host and external network.
When interface connected with the uplink is at the state of Down or Removed, the router actively lowers
its priority so that priority of other routers in the backup group will be higher. Thus the router with the
highest priority becomes the gateway for the transmission task.

4.2.6.4 WAN Failover
WAN failover refers to failover between Ethernet WAN interface and cellular interface. When service
transmission can’t be carried out normally due to malfunction of a certain interface or lack of bandwidth,
the rate of flow can be switched to backup interface quickly. Then the backup interface will carry out
service transmission and share network flow so as to improve reliability of communication of data
equipment.
When link state of main interface is switched from up to down, system will have the pre-set delay works
instead of switching to link of backup interface immediately. Only if the state of main interface is still
down after delay, will the system switch to link of backup interface. Otherwise, system will remain
unchanged.

4.2.7.2 RIP
RIP is mainly designed for small networks. RIP uses Hop Count to measure the distance to the destination
address, which is called Metric. In RIP, the hop count from the router to its directly connected network is 0
and the hop count of network to be reached through a router is 1 and so on. In order to limit the
convergence time, the specified metric of RIP is an integer in the range of 0 - 15 and the hop count larger
than or equal to 16 is defined as infinity, which means that the destination network or host is unreachable.
Because of this limitation, the RIP is not suitable for large-scale networks. To improve performance and
prevent routing loops, RIP supports split horizon function. RIP also introduces routing obtained by other
routing protocols.

4.2.7.3 OSPF
OSPF, short for Open Shortest Path First, is a link status based on interior gateway protocol developed by
IETF.
If a router wants to run the OSPF protocol, there should be a Router ID that can be manually configured. If
no Router ID configured, the system will automatically select an IP address of interface as the Router ID.
The selection order is as follows:
- If a Loopback interface address is configured, then the last configured IP address of Loopback
interface will be used as the Router ID;
- If no Loopback interface address is configured, the system will choose the interface with the biggest IP
address as the Router ID.
Five types of packets of OSPF:
-
Hello packet
DD packet (Database Description Packet)
LSR packet (Link-State Request Packet)
LSU packet (Link-State Update Packet)
LSAck packet (Link-Sate Acknowledgment Packet)
Neighbor and Neighboring
After OSPF router starts up, it will send out Hello Packets through the OSPF interface. Upon receipt of
Hello packet, OSPF router will check the parameters defined in the packet. If it’s consistent, a neighbor
relationship will be formed. Not all matched sides in neighbor relationship can form the adjacency
relationship. It is determined by the network type. Only when both sides successfully exchange DD
packets and LSDB synchronization is achieved, the adjacency in the true sense can be formed. LSA
describes the network topology around a router, LSDB describes entire network topology.

4.2.8.2 IPSec
IPsec is especially useful for implementing virtual private networks and for remote user access through
dial-up connection to private networks. A big advantage of IPsec is that security arrangements can be
handled without requiring changes to individual user computers.
IPsec provides three choices of security service: Authentication Header (AH), Encapsulating Security
Payload (ESP), and Internet Key Exchange (IKE). AH essentially allows authentication of the senders’ data.
ESP supports both authentication of the sender and data encryption. IKE is used for cipher code exchange.
All of them can protect one and more data flows between hosts, between host and gateway, and between
gateways.

4.2.8.3 GRE
Generic Routing Encapsulation (GRE) is a protocol that encapsulates packets in order to route other
protocols over IP networks. It’s a tunneling technology that provides a channel through which
encapsulated data message could be transmitted and encapsulation and decapsulation could be realized
at both ends.
In the following circumstances the GRE tunnel transmission can be applied:
- GRE tunnel could transmit multicast data packets as if it were a true network interface. Single use of
IPSec cannot achieve the encryption of multicast.
- A certain protocol adopted cannot be routed.
- A network of different IP addresses shall be required to connect other two similar networks.
