Users Guide

NOTE: The faster the convergence, the more frequent the route calculations and
updates. This behavior impacts CPU utilization and may impact adjacency
stability in larger topologies.
Generally, convergence level 1 meets most convergence requirements. Higher
convergence levels should only be selected following consultation with Dell
Networking technical support.
graceful-restart grace-period
Specifies the time duration, in seconds, that the router’s neighbors continue to advertise the router as fully
adjacent regardless of the synchronization state during a graceful restart.
NOTE
: This command enables OSPFv2 graceful restart globally by setting the grace period (in seconds)
that an OSPFv2 router’s neighbors continues to advertise the router as adjacent during a graceful restart.
