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.

Implementation Procedure

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If a route is withdrawn, added or carries a changed label, the device immediately sends an Update message to its peers, regardless of the peer route-update-interval configuration.

Example

# Set the interval at which routing updates are sent to a peer group to 10s.
