A service provider is implementing graceful protocol restart (GR) for BGP on a core router. The engineer wants to ensure that when the BGP process restarts, the peer does not immediately withdraw routes. Which configuration is required on the peer router?

Configure a longer BGP hold time on the peer.

Enable graceful restart on the peer and configure a restart time.

What is the primary purpose of Nonstop Active Routing (NSR) on Juniper devices?

To preserve Layer 2 bridging state during a Routing Engine switchover

To provide fast failure detection for neighboring routers

To enable continuous forwarding of traffic during a Routing Engine switchover

To maintain routing protocol state during a Routing Engine switchover

Which statement correctly describes a requirement for Graceful Protocol Restart (GR) to work effectively?

The device must have two Routing Engines installed

The device must be configured with nonstop active routing (NSR)

The neighboring routers must support the same GR capability

The device must run OSPF as the only routing protocol

A service provider has a pair of MX480 routers configured with GRES. The engineer wants to add NSR to ensure that BGP sessions are not disrupted during an RE switchover. What additional configuration is required?

Configure a redundant Ethernet (reth) interface for the BGP sessions.

Enable NSR on the BGP protocol.

Enable NSB on the BGP interfaces.

Enable GR for BGP on the peer routers.

Which feature is specifically designed to maintain Layer 2 bridging state during a Routing Engine switchover?
