Enabling Nonstop Routing for OSPFv2
This optional task describes how to enable nonstop routing (NSR) for OSPFv2 process. NSR is disabled by
default. When NSR is enabled, OSPF process on the active RP synchronizes all necessary data and states with
the OSPF process on the standby RP. When the switchover happens, OSPF process on the newly active RP
has all the necessary data and states to continue running and does not require any help from its neighbors.
Step 1

Step 3
nsr
Example:
RP/0/RSP0/CPU0:router(config-ospf)# nsr
