Step Command Remarks
2. Enter BGP view or BGP-VPN
instance view.
• Enter BGP view:
bgp as-number
• Enter BGP-VPN instance
view:
a. bgp as-number
b. ip vpn-instance
vpn-instance-name
N/A
3. 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.
If you modify the timers with the
peer timer
command, BGP
immediately closes the existing
BGP session and creates a new
session to the peer by using the
new settings.
The holdtime must be at least
three times the keepalive interval.
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):

3. Configure the interval for
sending updates for the
same route to a peer or peer
group.

seconds for an IBGP peer and 30
seconds for an EBGP peer.
