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, and • whichever is the lower value; one-third of the new holdtime value, or the configured keepalive value is the new keepalive value. neighbor update-source Enable the E-Series software to use Loopback interfaces for TCP connections for BGP sessions.
