Configure an I-SID List for an IPv4 IS-IS Accept Policy

Configures a list of I-SID numbers that represent local or remote Layer 3 VSNs to which the IS-IS accept policy applies. After you create the list of I-SID numbers, you must then create, configure, and enable the IS-IS accept policy.

Note

Note

When creating an I-SID list, you can add I-SID entries until the maximum limit for supported Layer 3 I-SIDs is reached. The system truncates any additional I-SID entries. The maximum limit includes the I-SIDs for locally configured Layer 3 VSNs and the I-SIDs specified for IS-IS accept policy filters.

Refresh the EDM tab to view the actual list of I-SIDs in the I-SID list.

Before you begin

  • Enable IS-IS globally.

  • Ensure the manual area exists.
