Apply IPv6 IS-IS Accept Policies Globally
Apply IPv6 IS-IS accept policies globally. Use IPv6 IS-IS accept policies to filter incoming IS-IS routes the device receives over the SPBM cloud.
After you apply the IPv6 IS-IS accept policy filters, the device removes and re-adds all IPv6 routes with updated filters.
IPv6 IS-IS accept policies are disabled by default.
Note
-
After you apply IPv6 IS-IS accept policies globally the application can disrupt traffic and cause temporary traffic loss. After you configure the IPv6 IS-IS accept policies value to Apply, the device reapplies the accept policies, which deletes all of the IPv6 IS-IS routes, and adds the IPv6 IS-IS routes again. You should make all the relevant accept policy changes, and then apply IPv6 IS-IS accept policies globally at the end.
-
If the route policy changes, you must reapply 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.
-
Ensure the IPv6 IS-IS filter exists.
-
Change the VRF instance as required to apply IPv6 IS-IS accept policies on a specific VRF instance. Not all parameters are configurable on non-default VRFs.
