Enabling disjoint backup paths for primary and standby SRLG disjoint configuration

About this task

The following details the steps necessary to create shared risk link groups for primary/standby SRLG disjoint configuration.

Procedure

  1. Create an SRLG-group similar to admin groups.
  2. Link the SRLG-group to MPLS interfaces.
  3. Configure primary and secondary LSP paths and enable SRLG on the secondary LSP path. Note that the SRLG secondary LSP paths will always perform a strict CSPF query. The srlg-frr command is irrelevant in this case (For more information, see srlg-frr).
