After a switchover, which command would you use to confirm that NSR operated correctly and the switchover was successful?

show configuration routing-options

How does Graceful Restart (GR) differ from NSR in handling protocol state during a switchover?

GR requires two Routing Engines, while NSR can work with a single RE.

GR relies on neighboring routers to maintain state and help the restarting router recover, while NSR maintains state locally on the standby RE.

GR is a Junos-specific feature, while NSR is a standard protocol.

GR preserves the forwarding table, while NSR preserves the routing table.

Which Junos CLI configuration statement is used to enable NSR?

set chassis redundancy graceful-switchover

set routing-options nonstop-routing

What is the primary purpose of Nonstop Active Routing (NSR) in Junos?

To preserve routing protocol state and adjacency during a Routing Engine switchover, preventing peer resets and route flapping.

To provide a backup copy of the configuration that can be manually restored after a switchover.

To reduce the number of Routing Engines required in a chassis by allowing a single RE to handle all protocols.

To enable faster software upgrades by allowing the standby RE to take over during a reboot.

A network engineer is configuring NSR on a dual-RE router. The engineer has enabled GRES and has confirmed that both REs are eligible. The engineer then executes the command 'set routing-options nonstop-routing'. What is the next step the engineer should take to complete the NSR configuration?

Reboot both Routing Engines to activate the NSR configuration.

Enable Graceful Restart for all routing protocols to complete the NSR configuration.

Configure the backup RE as the primary RE to complete the NSR configuration.

Commit the configuration and verify NSR status with 'show task replication'.
