The peer route-update-interval command sets the interval at which a device sends routing updates carrying the same prefix to a specified MBGP peer.
The undo peer route-update-interval command restores the default setting.
By default, the interval at which routing updates are sent to an IBGP peer is 15s, and the interval at which routing updates are sent to an EBGP peer is 30s.
| Parameter | Description | Value |
|---|---|---|
| peerIpv4Addr |
Specifies the IP address of an MBGP peer. |
The address is in dotted decimal notation. |
| interval |
Specifies the minimum interval at which MBGP routing updates are sent. |
The value is an integer ranging from 0 to 600, in seconds. The value 0 indicates that the device immediately sends BGP Update messages to notify its peers of route changes. |
Usage Scenario
When routes change, the device sends routing updates to notify its peers. If a route changes frequently, the peer route-update-interval command can be used to adjust the interval at which Update packets are sent for changes of this route. This frees the device from sending Update packets for every route change.
Prerequisites
An MBGP peer or peer group has been configured using the group and the peer group command.
If the peer route-update-interval command is used but no peer exists, a message is displayed, indicating that the peer does not exist.Precautions
If a route is removed or added, the device sends an Update (Withdraw) packet to its peers immediately, without waiting the interval set using the peer route-update-interval command to expire.
