Configuring OSPF Graceful Restart

One device can act as both a GR Restarter and GR Helper at the same time.
OSPF GR can be implemented through:
IETF standard GR capable routers. The GR restarter communicates with GR helpers by
exchanging Type-9 Opaque LSAs called Grace LSAs.
Non IETF standard GR capable routers. The GR restarter communicates with GR helpers by
exchanging OSPF messages that carry link local signaling (LLS) and out of band
re-synchronization (OOB) extension information.
Configuring the OSPF GR Restarter
You can configure the IETF standard or non IETF standard OSPF GR Restarter.
