Enabling TE Auto FRR

Procedure

1. Run system-view

   The system view is displayed.

2. Run mpls

   The MPLS view is displayed.

3. Run mpls te auto-frr [ self-adapting ]

   MPLS TE Auto FRR is enabled globally.

   To enable an automatic bypass tunnel to dynamically select node or link protection based on network conditions, configure self-adapting.

4. Run quit

   The system view is displayed again.

5. Run interface interface-type interface-number

   The view of the outbound interface of the primary tunnel is displayed.

6. (Optional) Run mpls te auto-frr { block | default | link | node | self-adapting }

   TE Auto FRR is enabled on the interface.

   The mpls te auto-frr default command is run for all MPLS TE-enabled interfaces after MPLS TE Auto FRR is enabled globally. To disable TE Auto FRR on interfaces, run the mpls te auto-frr block command on these interfaces. After the mpls te auto-frr block command is run on an interface, the interface is incapable of TE Auto FRR, regardless of whether TE Auto FRR is enabled or re-enabled globally.

   To enable an automatic bypass tunnel bound to the current tunnel to dynamically select node or link protection based on network conditions, configure self-adapting.

   

   • If the mpls te auto-frr default command is configured in the interface view, the Auto FRR capability on the interface is consistent with the global Auto FRR capability.

   • After node protection is enabled, if an automatic bypass tunnel cannot be established due to none available links, the penultimate hop (not other hops) on the primary tunnel attempts to establish an automatic bypass tunnel to implement link protection.

   • If the mpls te auto-frr node command without self-adapting configured is run, and the requirement for node protection is not met, the penultimate hop (but not other hops) on the primary tunnel attempts to set up an automatic bypass tunnel for link protection.

7. Run commit

   The configuration is committed.
