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.

In the navigation pane, expand Configuration > IPv6.
Select IS-IS.
Select the Accept Global tab.
Optional: Select a name from the list or enter name in the DefaultPolicyName field, to specify the route policy name for the default filter.
Select Apply to apply the default policy.
Select Apply.

Use the data in the following table to configure the Accept Global tab.


Name	Description
DefaultPolicyName	Specifies the route policy name for the default filter.
Apply	Applies the default policy when you select apply. The device only activates the default policy if the route map (the default policy name) has a value. If you do not select apply, the device takes no action. The GRT always returns no action.
NickNameTableSize	Shows the IPv6 IS-IS In Filter Nick Name table size.
IsidTableSize	Shows the IPv6 IS-IS In Filter I-SID table size.
NickNameIsidTableSize	Shows the IPv6 IS-IS In Filter Nick Name I-SID table size.
IsidListTableSize	Shows the IPv6 IS-IS In Filter I-SID List table size.
