Configure the keepalive
interval and hold time.
•
Configure the global
keepalive interval and hold
time:
timer keepalive keepalive
hold
holdtime
•
Configure the keepalive
interval and hold time for a
peer or peer group:
peer
{
group-name
|
ipv6-address
[
prefix-length
] }
timer
keepalive
keepalive
hold
holdtime
Use at least one method.
By default, the keepalive interval
is 60 seconds, and hold time is
180 seconds.
The
timer
command takes effect
for new BGP sessions and does
not affect existing sessions.
The timers configured with the
timer
and
peer timer
commands
do not take effect until a session is
re-established (for example, a
session is reset).
The hold time must be at least
three times the keepalive interval.
Setting the session retry timer
About setting the session retry timer
To speed up session establishment to a peer or peer group, set a small session retry timer. If the
BGP session flaps, you can set a large session retry timer to reduce the impact and speed up route
convergence.
Restrictions and guidelines
The timer set by the
peer timer connect-retry
command takes precedence over the timer set by the
timer connect-retry
command.
