Usage Information
This command enables soft-reconfiguration for the BGP neighbor specified. BGP stores all the updates the
neighbor receives but does not reset the peer-session.
You cannot set this configuration for a peer that is associated with a peer group. Similarly, you cannot associate a
peer to a peer group if that peer is already configured with these settings.
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 Configuration mode for IPv4 Unicast address only.

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.
Defaults
• keepalive = 60 seconds
• holdtime = 180 seconds
