8.14.3 Configuring BGP Keepalive and Hold Timers

The values of BGP Keepalive and hold timers determine the speed at which BGP detects network
faults. You can adjust the values of these timers to improve network performance.
Context
Keepalive messages are used by BGP to maintain peer relationships. After establishing a BGP
connection, two peers periodically send Keepalive messages to each other to detect BGP peer
relationship status. If a device receives no Keepalive message from its peer after the hold timer
expires, the device considers the BGP connection to be closed.
