Parameters
group-name

group must have been created.
ip-address

interval

Usage guidelines
A BGP router sends an update message to its peers when a route is changed. If the route changes
frequently, the BGP router sends many updates for the route, resulting in routing flaps. By configuring the
interval for sending the same update to a peer or peer group, you can avoid such routing flaps.
Examples
# In BGP view, specify the interval for sending the same update to peer group
test
as 10 seconds.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] peer test as-number 100
[Sysname-bgp] peer test route-update-interval 10
# In BGP-VPN instance view, specify the interval for sending the same update to peer group
test
as 10
seconds.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ip vpn-instance vpn1
[Sysname-bgp-vpn1] peer test route-update-interval 10
