Routing Policy Configuration for EBGP Peer Routing Advertisements

A

The correct answer is C. The new policy should be applied as an export policy for the specific EBGP peer.

Explanation:

In BGP (Border Gateway Protocol), a routing policy is a set of rules that dictate how BGP should handle incoming and outgoing routing updates. BGP routing policies are typically used to filter routes, manipulate route attributes, and influence the path selection process.

In this scenario, the requirement is to configure and apply a new routing policy to influence routing advertisements sent to a specific EBGP peer, without impacting routing advertisements sent to any other peer. To achieve this, the new policy must be applied as an export policy for the specific EBGP peer.

When a BGP router sends updates to its peers, it applies the export policies that are defined for that peer or peer group. An export policy is a set of rules that determines which routes should be advertised to a specific peer or peer group, and how those routes should be modified before being sent.

Applying the new policy as an export policy for the specific EBGP peer ensures that only that peer is affected by the policy. The policy will modify the routing advertisements that are sent to that peer, without affecting any other peers or peer groups.

Therefore, option C is the correct answer. Option A would apply the policy to all peers in the EBGP group, which is not the desired outcome. Option B and D would apply the policy to incoming updates from the specific peer, rather than outgoing updates to the specific peer, which is also not the desired outcome.
