Network

An engineer is deploying a new BGP peering in a new data center. The engineer configured the BGP session to peer with the remote endpoint. As soon as the BGP peers try to exchange routing prefixes, one peer drops the connection. After reviewing the configuration and logging messages, the engineer finds that the router is not receiving keepalives from the remote endpoint and terminates the session. Which action resolves the issue?

Explanation

BGP maintains an established session by receiving KEEPALIVE or UPDATE messages before the negotiated hold timer expires. Configuring higher, compatible keepalive and hold-down timer values on both peers prevents premature hold-timer expiration when keepalives are arriving too slowly.
