What is the primary purpose of BGP multipath in a Junos OS environment?

To reduce the number of IBGP sessions required in a full mesh

To enable load balancing across multiple equal-cost BGP paths

To suppress unstable routes that flap

To establish BGP sessions between non-directly connected peers

A service provider has two BGP routers in different autonomous systems that are not directly connected. The network between them is a transit network that does not run BGP. The provider needs to establish an EBGP session between these two routers. What must be configured to allow the BGP session to be established?

Configure the 'local-address' statement to specify the source IP address.

Configure the 'multihop' statement with the appropriate TTL value under the BGP group.

Configure the 'export' policy to advertise the routes.

Configure the 'passive' statement under the BGP group.

A service provider has two BGP routers in different autonomous systems that are not directly connected. The provider has configured BGP multihop with a TTL of 2. However, the BGP session is not establishing. What is the most likely reason for this?

The 'passive' statement is not configured.

The 'export' policy is not configured.

The 'multihop' statement is not configured on both routers.

The 'local-address' statement is not configured.

In a hierarchical BGP route reflection design, what is the primary benefit of using multiple levels of route reflectors?

It allows the IBGP network to scale to a larger number of routers

It eliminates the need for BGP multipath

It allows BGP sessions to be established over multiple hops

It automatically enables route damping

In BGP route damping, what happens when a route's penalty exceeds the suppress threshold?

The route is removed from the routing table

The route is immediately reused

The route is marked as preferred

The route is suppressed and not advertised
