Hi guys,
Was just looking to see if anyone can explain why and how NSR happens in a dual RP system.
For example between a PE-CE (EBGP)
and when running with OSPF and ISIS?
Solved! Go to Solution.

Hello @nwekechampion,
In the context of VSS or StackWise Virtual, NSR ensures that routing and forwarding are maintained even if one RP in the same device fails.
With PE-CE connections using BGP, OSPF, or ISIS, NSR ensures that BGP sessions are maintained, and BGP
adjacencies
are quickly re-established on the standby RP in case of an RP failure. Also, NSR ensures that OSPF/ISIS
adjacencies
and link state databases are synchronized, allowing for a smooth transition of control plane operations to the standby RP in the event of a failure.

NSR happened between RP in same device or device that run vss or stackwise virtual
It not happend between two different standalone devices.
