A network administrator is configuring GRES on a Juniper router with dual Routing Engines. The administrator has already enabled GRES at the [edit chassis redundancy] hierarchy. What additional configuration step is required to complete the GRES configuration?

Commit the configuration on both Routing Engines.

Enable GRES on the backup RE separately using the same command.

Commit the configuration and reboot both Routing Engines.

Configure the backup RE as the master using the set chassis redundancy master command.

What is a consequence of GRES not preserving routing protocol state?

Routing protocols must re-establish their adjacencies and reconverge after a switchover

The configuration is lost after a switchover

The router cannot forward packets during the switchover

The forwarding table is cleared after a switchover

A network engineer is troubleshooting a router that has GRES enabled. The engineer triggers a manual RE switchover and notices that some BGP sessions are flapping. The forwarding plane continues to forward traffic without interruption. What is the most likely cause of the BGP session flapping?

The forwarding table was not synchronized to the backup RE.

The router is not configured with NSR.

The backup RE does not have the same hardware as the master RE.

GRES does not preserve BGP protocol state, so BGP sessions restart after the switchover.

Which limitation is associated with GRES?

It only works with OSPF and IS-IS

It requires a reboot of the router to take effect

It does not preserve routing protocol state information

It cannot be used with virtual chassis
