Configure an IS-IS Accept Policy to Apply for a Specific I-SID
Configure an IS-IS accept policy for a specific I-SID number to represent a local or remote Layer 3 VSN, which allows the system to redistribute the remote VSN to the VSN where you applied the filter. An I-SID value of 0 represents the global routing table (GRT).
