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 configured with the neighbor timers command override the timer values configured with any
other command.
When two neighbors, configured with different keepalive and holdtime values, negotiate for new values, the
resulting values are as follows:
• the lower of the holdtime value is the new holdtime value, and
• whichever is the lower value; one-third of the new holdtime value, or the configured keepalive value, is
the new keepalive value.
neighbor update-source
Enable the system to use Loopback interfaces for TCP connections for BGP sessions.

source interface command.
