Configure an IPv4 IS-IS Accept Policy for a Specific Advertising BEB and I-SID
Configures a specific advertising Backbone Edge Bridge (BEB) with a specific I-SID to allow you to apply the IS-IS accept policy to routes for a specific advertising BEB.

Note
If the route policy changes, you must re-apply the IS-IS accept policy, unless it was the last sequence in the configuration.
