no

command to restore the timers to the default value.

Default
KEEP-ALIVE
: 60 seconds
HOLD-TIME
: 180 seconds
Command Mode
Router configuration.
Usage Guideline
The suggested default value for the KEEPALIVE is one third (1/3) of the
HOLDTIME. The timers configured for a specific neighbor or peer group (by the
command
"neighbor timers” on page 453
) overrides the timers configured for
all BGP neighbors using the
timers bgp
command.
When the minimum acceptable HOLD-TIME is configured on a BGP router, a
remote BGP peer session is established only if the remote peer is advertising a
HOLD-TIME that is equal to, or greater than, the minimum acceptable HOLD-
TIME interval. If the minimum acceptable HOLD-TIME interval is greater than the
configured HOLD-TIME, the next time the remote session tries to establish, it will
fail and the local router will send a notification stating
unacceptable hold time
.
Example
This example shows how to change the
KEEP-ALIVE
timer to 50 seconds and
the
HOLD-TIME
timer to 150 seconds:
