Adjusting Bgp Timers - Motorola BSR 2000 Configuration And Management Manual

Release 1.0

Adjusting BGP Timers

BGP supports the following two commands that set the frequency of keepalive and
holdtime timers:
Keepalive messages are exchanged between BGP peers or peer groups to monitor the
health of the link between them. If a BGP peer does not receive a keepalive message,
it waits for a configured holdtime before the ailing BGP peer is declared dead by its
waiting peer.
Use the timers bgp command in Router Configuration mode to configure the
keepalive frequency and holdtime interval globally for BGP:
MOT(config-bgp)#timers bgp <0-21845> [<0-65535>]
where:
Use the neighbor timers command in Router Configuration mode to configure the
keepalive frequency and holdtime interval for a BGP peer or peer-group:
MOT(config-bgp)#neighbor [<A.B.C.D> | <WORD>] timers <0-21845>
[<0-65535>]

timers bgp — globally sets the keepalive timers for BGP
neighbor timers — sets the keepalive timers for a BGP peer or peer group
0-21845 is the frequency in seconds that the BSR sends keepalive messages to its
peers. The default is 60 seconds.
0-65535 is the optional holdtime, which is the interval in seconds, after which,
not receiving a keepalive or any other BGP message, the BSR declares a BGP
peer dead.
A.B.C.D is the IP address of the BGP peer.
WORD is the name of the BGP peer group.
0-21845 is the frequency, in seconds, that the BSR sends keepalive messages to
its peers. The default is 60 seconds.
0-65535 is the interval a BSR waits to receive a keepalive message before it
declares a BGP peer dead. The default is 180 seconds.
