Usage Guidelines
This command configures the router as a graceful OSPF restart helper router for a single or multiple
routers. When the router is acting as a helper, it will continue to advertise the restarting router as if it
was fully adjacent.
One OSPF interface may not help more than one restarting router. An OSPF interface may not enter
helper mode when the router is performing a graceful restart. All the interfaces to a neighbor router
must be configured as graceful restart helpers, or the router will not support graceful restart for its
neighbor.
Example
The following command configures a router to be a graceful OSPF helper router for planned restarts for
all routers in area 10.20.30.40:
configure ospf area 10.20.30.40 restart-helper planned
