Usage
Information
By default, OSPFv3 graceful restart is disabled and functions only in a helper role to
help restarting neighbor routers in their graceful restarts when it receives a Grace
LSA.
When configured in a helper-reject role, an OSPFv3 router ignores the Grace LSAs
that it receives from a restarting OSPFv3 neighbor.
The graceful-restart role command is not supported in OSPFv3. When you enable
the helper-reject role on an interface, you reconfigure an OSPFv3 router to
function in a “restarting-only” role.
ipv6 ospf hello-interval
Specify the time interval between the hello packets sent on the interface.
Z9500
Syntax
ipv6 ospf hello—interval seconds
