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 will be as follows:
• the lower of the
holdtime values 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.
