Configuring Ospf Graceful Restart; Configuring The Ospf Gr Restarter - HP MSR2000 series Configuration Manual

Configuring OSPF Graceful Restart

OSPF GR involves the following:
IETF standard GR—Uses Opaque LSAs to implement GR.
•
Non IETF standard GR—Uses link local signaling (LLS) to advertise GR capability and uses out of
•
band synchronization to synchronize the LSDB.
A device can act as a GR Restarter and GR Helper at the same time.

Configuring the OSPF GR Restarter

You can configure the IETF standard or non IETF standard OSPF GR Restarter.
Configuring the IETF standard OSPF GR Restarter
Step
1. Enter system view.
2. Enable OSPF and enter its
view.
3. Enable opaque LSA
advertisement capability.
4. Enable the IETF standard
Graceful Restart capability.
5. Configure the Graceful Restart
interval.
Configuring the non-IETF standard OSPF GR Restarter
Step
1. Enter system view.
2. Enable OSPF and enter its
view.
3. Enable the link-local signaling
capability.
4. Enable the out-of-band
re-synchronization capability.
5. Enable non-IETF standard
Graceful Restart capability for
OSPF.
6. Configure Graceful Restart
interval for OSPF.
