Usage Information
Timer values congured with the neighbor timers command override the timer values congured with the
timers bgp command.
When two neighbors, congured with dierent 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 congured keepalive value is the new
keepalive value
