# Configure ACL 3000 to permit only route 113.0.0.0/16. Use ACL 3000 to filter inbound routes. system-view [Sysname] acl number 3000 [Sysname-acl-adv-3000] rule 10 permit ip source 113.0.0.0 0 destination 255.255.0.0 0 [Sysname-acl-adv-3000] rule 100 deny ip [Sysname-acl-adv-3000] quit [Sysname] ospf 100 [Sysname-ospf-100] filter-policy 3000 import graceful-restart (OSPF view) Use graceful-restart to enable OSPF GR. Use undo graceful-restart to disable OSPF GR. Syntax graceful-restart [ ietf | nonstandard ] [ global | planned-only ] * undo graceful-restart Default OSPF GR is disabled. Views OSPF view Predefined user roles network-admin Parameters ietf: Enables IETF GR. nonstandard: Enables non-IETF GR. global: Enables global GR. In global GR mode, a GR process can be completed only when all GR Helpers exist. A GR process fails if a GR Helper fails (for example, the interface connected to the GR Helper goes down). Without this keyword, this command enables partial GR. In partial GR mode, a GR process can be completed if a GR Helper exists. planned-only: Enables planned only GR. Without this keyword, this command enables both planned GR and unplanned GR. Usage guidelines GR includes planned GR and unplanned GR: • Planned GR-Manually restart OSPF. Before OSPF restart, the GR Restarter sends Grace-LSAs to GR Helpers. • Non-planned GR-OSPF restarts because of device failure. Before OSPF restart, the GR Restarter does not send Grace-LSAs to GR Helpers. Before enabling IETF GR for OSPF, enable Opaque LSA advertisement and reception with the opaque-capability enable command. Before enabling non-IETF GR for OSPF, enable OSPF LLS with the enable link-local-signaling command and OOB-Resynch with the enable out-of-band-resynchronization command. 98
