Usage guidelines
After establishing a BGP session, two routers send keepalive messages at the specified keepalive interval
to each other to keep the session.
If a router receives no keepalive or update message from the peer within the holdtime, it tears down the
session.
Use the timer command to configure the keepalive interval and holdtime for all BGP peers. Use the peer
timer command to configure the keepalive interval and holdtime for a peer or peer group. If both
commands are configured, the intervals configured by the peer timer command have higher priority.
If the holdtime settings on the local and peer routers are different, the smaller one is used.
If the holdtime is configured as 0, no keepalive message will be sent to the peer, and the peer session will
never time out. If the keepalive interval is configured as 0 and the negotiated holdtime is not 0, one third
of the holdtime is taken as the interval for sending keepalive messages. If neither the holdtime nor the
