Configure an IPv4 IS-IS Accept Policy for a Specific Advertising BEB and I-SID-list
Configure an IS-IS accept policy to apply to a specific advertising Backbone Edge Bridge (BEB) for a specific I-SID list to represent local or remote Layer 3 VSNs, which allows the system to redistribute the remote VSNs to the VSN where you applied the filter.
Note
If the route policy changes, you must reapply the IS-IS accept policy, unless it was the last sequence in the configuration.
Before you begin
-
Enable IS-IS globally.
-
Ensure the manual area exists.
-
You must configure a route-map to apply.
