Enabling OSPFv3 NSR

OSPFv3 non-stop routing (NSR) can be re-enabled if it has been disabled. The following task re-enables NSR for OSPFv3.
  1. Enter the configure terminal command to access global configuration mode. 
    device# configure terminal
  2. Enter the ipv6 router ospf command to enter OSPFv3 router configuration mode and enable OSPFv3 globally. 
    device(config)# ipv6 router ospf
  3. Enter the nonstop-routing command to re-enable NSR on the device. 
    device(config-ospf6-router)# nonstop-routing

The following example re-enables NSR for OSPFv3. 

device# configure terminal
device(config)# ipv6 router ospf 
device(config-ospf6-router)# nonstop-routing
