routers within the peer group.

keepalive messages sent to the neighbor routers. The range

60 seconds
.
holdtime
Enter a number for the time interval, in seconds, between
the last keepalive message and declaring the router dead.

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.
