ip-address: Specifies a peer by its IP address. The peer must have been created.

ipv6-address: Specifies a peer by its IPv6 address. The peer must have been created.

interval: Specifies a minimum interval for sending the same update message. The range is 0 to 600 seconds.

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
