Which configuration can enable indirectly connected EBGP peers to establish a connection normally?

To enable indirectly connected EBGP (External Border Gateway Protocol) peers to establish a connection normally, configuring the "peer ebgp-max-hop" setting is essential. This configuration allows the EBGP session to work over multiple hops, which is necessary when the peers are not directly connected.

In standard EBGP operation, neighbors must be directly connected to establish a session, as EBGP typically expects the peers to be on the same subnet. However, with the "peer ebgp-max-hop" configuration, the router can specify the maximum number of hops it should traverse to reach the EBGP neighbor. This effectively enlarges the scope of the search for the peer, allowing it to reach routers that are several hops away, thus facilitating the establishment of connections that would otherwise not be possible under the default conditions.

Other options, while relevant, do not specifically address the requirement for indirectly connected peers. For instance, some might relate to setting specific functionalities or characteristics of the EBGP session but do not extend the reach to indirectly connected peers as "peer ebgp-max-hop" does. This makes the latter the correct choice for enabling EBGP connections between routers that are not directly adjacent.
