If both the peers negotiate with different keepalive and hold time values, the final hold time value is the lowest values received. The new keepalive value is one-third of the accepted hold time value. ● Configure timer values for all neighbors in ROUTER-NEIGHBOR mode. timers keepalive holdtime ○ keepalive - Time interval in seconds, between keepalive messages sent to the neighbor routers (1 to 65535, default 60). ○ holdtime - Time interval in seconds, between the last keepalive message and declaring the router dead (3 to 65535, default 180).
