What happens to protocol adjacencies (e.g., OSPF neighbors) during an NSR switchover?

They are maintained because the standby RE has the same protocol state and continues sending keepalives.

They are temporarily suspended until the new active RE re-establishes them.

They are reset, and the protocols reconverge from scratch.

They are converted to passive adjacencies to avoid detection.

In which scenario might NSR not be effective?

When a routing protocol does not support state synchronization, such as certain multicast protocols.

When the network uses OSPF as the IGP.

When the device is running a recent version of Junos.

When the device has two Routing Engines.

After a forced switchover on a dual-RE router configured with NSR, a network engineer wants to confirm that the switchover was successful and that NSR is still functioning on the new primary RE. Which set of commands should the engineer use to verify this?

show route summary and show bgp summary

show chassis routing-engine and show task replication

show log messages and show interfaces terse

show system uptime and show version

A network engineer is configuring NSR on a dual-RE MX router that runs BGP, OSPF, and IS-IS. After enabling NSR at the [edit routing-options] hierarchy, the engineer wants to verify that all three protocols are actually being synchronized to the backup RE. Which command should the engineer use to confirm per-protocol NSR synchronization status?
