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
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
- In the navigation pane, expand .
- Select IS-IS.
- Select the Accept Isid tab.
- Select Insert.
- In the Isid field, specify the I-SID value.
- Select Enable to apply the filter.
- Optional: In the PolicyName field, specify the route-map name.
- Select Insert.
