segment-routing ipv6
3. Configure the TTL processing mode of SRv6 TE policies. ttl-mode { pipe | uniform }
By default, the TTL processing mode of SRv6 TE policies is pipe.
Configuring SRv6 TE policy CBTS
Prerequisites
Before configuring CBTS, you must create QoS traffic behaviors to mark the MPLS TE service class values for packets. For more information, see QoS configuration in ACL and QoS Configuration
Guide .
Procedure
1. Enter system view. system-view
2. Enter SRv6 view. segment-routing ipv6
3. Enter SRv6 TE view. traffic-engineering
4. Enter SRv6 TE policy view. policy policy-name
5. Set a service class value for the SRv6 TE policy.
service-class service-class-value
By default, no service class value is set for an SRv6 TE policy.
Enabling the device to drop traffic when an SRv6
TE policy becomes invalid
About this task
Enable this feature for an SRv6 TE policy if you want to use only the SRv6 TE policy to forward traffic.
By default, if all forwarding paths of an SRv6 TE policy become invalid, the device forwards the packets through IPv6 routing table lookup based on the packet destination IPv6 addresses.
After you execute the drop-upon-invalid enable command, the device drops the packets if all forwarding paths of the SRv6 TE policy become invalid.
Restrictions and guidelines
The drop-upon-invalid enable command does not take effect in the following cases:
•
BSID request failed or BSID conflicted for the SRv6 TE policy. To view the BSID request state, see the Request state field in the display segment-routing ipv6 te policy command output.
•
The SRv6 TE policy is invalid. To check the SRv6 TE policy validity, see the Forwarding index field in the display segment-routing ipv6 te policy command output. If the value is 0, the SRv6 TE policy is invalid.
