Adjusting Bgp Timers - Cisco NCS 6000 Series Configuration Manual

Implementing BGP

Adjusting BGP Timers

Perform this task to set the timers for BGP neighbors.
BGP uses certain timers to control periodic activities, such as the sending of keepalive messages and the
interval after which a neighbor is assumed to be down if no messages are received from the neighbor during
the interval. The values set using the timers bgp command in router configuration mode can be overridden
on particular neighbors using the timers command in the neighbor configuration mode.

DETAILED STEPS
Command or Action
Step 1 configure
Step 2 router bgp as-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 123
Step 3
timers bgp keepalive hold-time
Example:
RP/0/RP0/CPU0:router(config-bgp)# timers bgp 30 90
Step 4 neighbor ip-address
Example:
RP/0/RP0/CPU0:router(config-bgp)# neighbor
172.168.40.24
Step 5 timers keepalive hold-time
Example:
RP/0/RP0/CPU0:router(config-bgp-nbr)# timers 60
220
Step 6
commit
Purpose
Specifies the autonomous system number and enters the
BGP configuration mode, allowing you to configure the
BGP routing process.
Sets a default keepalive time and a default hold time for all
neighbors.
Places the router in neighbor configuration mode for BGP
routing and configures the neighbor IP address as a BGP
peer.
(Optional) Sets the keepalive timer and the hold-time timer
for the BGP neighbor.
