(Optional) Configuring GR Session Parameters on the Helper
Procedure
- Run system-view
The system view is displayed.
- Run ospf [process-id]
The OSPF view is displayed.
- Run graceful-restart helper-role { [ { ip-prefix ip-prefix-name | acl-number acl-number | acl-name acl-name } | ignore-external-lsa | planned-only ] * | never }
GR session parameters are configured on the Helper.
- If ACL parameters are configured, the local router can enter the Helper mode only after neighbors pass the filtering policies of ip-prefix or acl.
- If ignore-external-lsa is configured, the Helper does not check the LSAs outside the AS (AS-external LSA). By default, the Helper checks the LSAs outside the AS.
- If planned-only is configured, the Helper supports only planned GR. By default, the Helper supports both planned GR and unplanned GR.
- If never is configured, the router will not enter the Helper mode.
