Usage Information
Timer values congured with the neighbor timers command override the timer values congured with
any other 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 value is the new holdtime value, and
• whichever is the lower value; one-third of the new holdtime value, or the congured keepalive
value, is the new keepalive value.
