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
}
timer
keepalive
keepalive
hold
holdtime
Use either 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
reestablished (for example, a
session is reset).
Configuring the interval for sending updates for the same route
A BGP router sends an update message to its peers when a route is changed. If the route changes
frequently, the BGP router keeps sending updates for the same route, resulting route flapping. To prevent
this situation, perform this task to configure the interval for sending updates for the same route to a peer
or peer group.
To configure the interval for sending the same update to a peer or peer group (IPv4 unicast/multicast
address family):
