Configure an IPv4 IS-IS Accept Policy for a Specific I-SID List
Configure an IS-IS accept policy 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 re-apply 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.
