DETAILED STEPS
Configuring the Helper Level of the Router
This section describes the task of disabling the helper mode on the current router. By default, a router
that is capable of doing an OSPFv3 graceful restart is also enabled to be a helper to a node in graceful
mode. The graceful-restart helper command lets you disable the current router’s helper capability.
