During a Graceful Restart, what role does a neighboring router play?

It flushes its entire routing table and rebuilds it from the restarting router

It continues to advertise routes to the restarting router and keeps the adjacency active for a grace period

It immediately removes all routes learned from the restarting router

It takes over the restarting router's forwarding responsibilities

A network operator is troubleshooting a BGP Graceful Restart issue. The router is configured with GR, and the peer supports GR. However, when the peer restarts, the local router withdraws the routes immediately. The 'show bgp neighbor' output shows 'Restart time: 0'. What is the most likely cause?

The peer did not advertise a non-zero restart time in its GR capability.

The BGP session is not using TCP MD5 authentication.

The local router's stale route timer is set to 0.

The local router's GR helper mode is disabled.

A network engineer is troubleshooting a BGP session that went down on a Juniper router. The logs show that the peer sent a 'Restarting' capability and the local router acted as a helper. During the restart, the local router continued to advertise the peer's routes to other BGP neighbors. What is the most likely reason the local router was able to do this?

The local router kept the BGP routes in its routing table and marked them as stale, continuing to advertise them while the peer restarted.

The local router had pre-computed backup paths using BGP multipath and switched to them instantly.

The local router had a redundant Routing Engine that took over the BGP session immediately.

The local router used BFD to detect the restart and immediately recalculated all alternate paths.

Which Junos configuration statement enables Graceful Restart for BGP?

set protocols bgp graceful-restart

An engineer is troubleshooting a BGP Graceful Restart issue. The router is configured with GR, but when a peer restarts, the local router withdraws the routes instead of keeping them. Which command output would help determine if the local router is actually acting as a helper?
