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):
1. Enter system view.
N/A
2. Enter BGP instance view or
BGP-VPN instance view.
• Enter BGP instance view:
bgp as-number [ instance
instance-name ]
• Enter BGP-VPN instance
view:
a. bgp as-number
[ instance
instance-name ]
b. ip vpn-instance
N/A
3. Configure the interval for
sending updates for the
same route to a peer or peer
group.
peer
{ group-name | ipv4-address
[ mask-length ] }
route-update-interval
interval
By default, the interval is 15
seconds for an IBGP peer and 30
seconds for an EBGP peer.
To configure the interval for sending the same update to a peer or peer group (IPv6 unicast/multicast
address family):
1. Enter system view.
system-view
N/A
2. Enter BGP instance view or
BGP-VPN instance view.
• Enter BGP instance view:
bgp as-number [ instance
instance-name ]
• Enter BGP-VPN instance
view:
a. bgp as-number
[ instance
instance-name ]
b. ip vpn-instance
N/A
3. Configure the interval for
sending updates for the
same route to a peer or peer
group.
peer
{ group-name | ipv6-address
[ prefix-length ] }
route-update-interval
interval
By default, the interval is 15
seconds for an IBGP peer and 30
seconds for an EBGP peer.
