R0106-HP MSR Router Series Layer 3 - IP Routing Command Reference(V7)

148
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.
If you do not provide the nonstandard or ietf keyword, the command enables non-IETF GR for OSPF.
OSPF GR and OSPF NSR are mutually exclusive, so do not configure the graceful-restart command and
the non-stop-routing command at the same time.
Examples
# Enable IETF GR for OSPF process 1.
<Sysname> system-view
[Sysname] ospf 1
[Sysname-ospf-1] opaque-capability enable
[Sysname-ospf-1] graceful-restart ietf
# Enable non-IETF GR for OSPF process 1.
<Sysname> system-view
[Sysname] ospf 1
[Sysname-ospf-1] enable link-local-signaling
[Sysname-ospf-1] enable out-of-band-resynchronization
[Sysname-ospf-1] graceful-restart nonstandard
