Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
This command enables soft-reconguration for the BGP neighbor specied. BGP stores all the updates the
neighbor receives but does not reset the peer-session.
CAUTION: Inbound update storage is a memory-intensive operation. The entire BGP update database
from the neighbor is stored in memory regardless of the inbound policy results applied on the neighbor.
NOTE: This command is supported in BGP Router Conguration mode for IPv4 Unicast address
only.
Related Commands show ip bgp neighbors — displays routes received by a neighbor.
neighbor timers
Set keepalive and hold time timers for a BGP neighbor or a peer group.
Syntax
neighbor {ip-address | peer-group-name} timers keepalive holdtime
To return to the default values, use the no neighbor {ip-address | peer-group-name} timers
command.
Parameters
ip-address Enter the IP address of the peer router in dotted decimal format.
peer-group-name Enter the name of the peer group to set the timers for all routers within the peer group.
keepalive Enter a number for the time interval, in seconds, between keepalive messages sent to the
neighbor routers. The range is from 1 to 65535. The default is 60 seconds.
holdtime Enter a number for the time interval, in seconds, between the last keepalive message and
declaring the router dead. The range is from 3 to 65535. The default is 180 seconds.

Usage Information
Timer values congured with the neighbor timers command override the timer values congured with any
other command.
When two neighbors, congured with dierent keepalive and holdtime values, negotiate for new values, the
resulting values are as follows:
