Refer to the exhibits. The network administrator needs to set up BGP between the two company switches, Switch-1 and Switch-2. The BGP connection does not establish. Based on the exhibits, what does…

Question

Explanation

The BGP configuration shown uses the loopback addresses (10.0.0.1 and 10.0.0.2) for peering between Switch-1 and Switch-2. When using loopback interfaces for BGP peering, the BGP process needs to be explicitly told to use the loopback interface's IP address as the source for the BGP TCP connection. This is done with the update-source command.

On Switch-1:

router bgp 46500
 neighbor 10.0.0.2 remote-as 46500
 neighbor 10.0.0.2 update-source Loopback0

On Switch-2:

router bgp 46500
 neighbor 10.0.0.1 remote-as 46500
 neighbor 10.0.0.1 update-source Loopback0

(Assuming 'Loopback0' is the name of the loopback interface on both switches.)
