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. 382 Border Gateway Protocol
