9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
This command enables soft-reconguration for the BGP neighbor specied. 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 Conguration 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.

neighbor routers. The range is from 1 to 65535. The default is 60 seconds.
