Which statement is correct about graceful Routing Engine switchover (GRES)?
Which statement is correct about graceful Routing Engine switchover (GRES)?
When combined with Nonstop Routing (NSR), graceful Routing Engine switchover (GRES) ensures that routing information is preserved and the new master Routing Engine does not need to restart the Routing Protocol Daemon (rpd). This allows for minimal disruption in network operations during a switch.
The correct statement regarding graceful Routing Engine switchover (GRES) is: C. When combined with NSR, routing is preserved and the new master RE does not restart rpd. This combination of Graceful Routing Engine Switchover (GRES) with Nonstop Routing (NSR) helps in preserving routing information and ensures that the new master Routing Engine (RE) does not have to restart the Routing Protocol Daemon (RPD).
C GRES does not preserve the control plane, so NSR is need to preserve the control plane
C is correct
