Configure an IPv6 IS-IS Accept Policy for a specific I-SID

Configure an IPv6 IS-IS accept policy for a specific I-SID 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

Note

If the route policy changes, you must re-apply the IPv6 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.

  • Change the VRF instance as required to configure an IPv6 IS-IS accept policy for a particular I-SID on a specific VRF instance. Not all parameters are configurable on non-default VRFs.

Procedure

  1. In the navigation pane, expand Configuration > IPv6.
  2. Select IS-IS.
  3. Select the Accept Isid tab.
  4. Select Insert.
  5. In the Isid field, specify the I-SID value.
  6. Select Enable to apply the filter.
  7. Optional: In the PolicyName field, specify the route-map name.
  8. Select Insert.
