Parameters

Parameter	Description	Value
ipv6-address	IPv6 peer address.	The value is a 32-digit hexadecimal number, in the format of X:X:X:X:X:X:X:X.
interval	Specifies the minimum interval at which 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 Guidelines

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.

Precautions

If a route is withdrawn, the device immediately sends an Update message to its peers, regardless of the peer route-update-interval configuration. If a route is added and the interval between the last route addition time and the current route addition time is greater than the interval configured using the peer route-update-interval command, the device immediately sends an Update message to its peers. If a route is added and the interval between the last route addition time and the current route addition time is less than the interval configured using the peer route-update-interval command, the device sends an Update message to its peers only after the configured interval expires.

Example

# Set the interval at which routing updates are sent to a peer to 60s.
