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.

Procedure

In the navigation pane, expand Configuration > IP.
Click IS-IS.
Click the Accept Isid-List tab.
Click Insert.
In the Name field, specify the I-SID list name.
Select enable in the Enable check box to enable the filter.
In the PolicyName field, specify the route-map name.
Click Insert.
