• keepalive-The time, in seconds, between BGP KEEPALIVE packets sent to a neighbor. The range is 0 to 65,535 seconds. A small internal jitter is applied to the keepalive interval timer in order to reduce the CPU load that may occur when multiple timers expire simultaneously. • holdtime-The time, in seconds, that BGP continues to consider a neighbor to be alive without receiving a BGP KEEPALIVE or UPDATE packet from the neighbor. If no KEEPALIVE is received from a neighbor for longer than the hold time, BGP drops the adjacency. If the hold time is set to 0, then BGP does not enforce a hold time and BGP does not send periodic KEEPALIVE messages. The range is 0, 3 to 65,535 seconds. Default Configuration The keepalive and hold timers default to the globally configured values set with the timers bgp command. Command Mode BGP Router Configuration mode, IPv4 Address Family Configuration mode User Guidelines The new values are not applied to adjacencies already in the ESTABLISHED state. Updated keepalive or hold time values are only applied when an adjacency is newly formed. Command History Introduced in version 6.2.0.1 firmware. Updated in version 6.3.0.1 firmware. Example console(config-router)#neighbor 10.130.14.55 timers 1000 500 neighbor update-source The neighbor update-source command configures BGP to use a specific IP address as the source address for the TCP connection with a neighbor. This IP address must be the IP address configured on the peer BGP router as the neighbor address for this router. Layer 3 Routing Commands 1330
