Usage Information
Timer values configured with the neighbor timers command override the timer
values configured with the timers bgp 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 values is the new holdtime value
• whichever is the lower value; one-third of the new holdtime value, or the
configured keepalive value is the new keepalive value
