Configuring the interval for sending the same update
A BGP router sends an update message to its peers when a route is changed. If the route changes
frequently, the BGP router sends a large number of updates for the route, which can cause route flaps.
This task allows you to configure the interval for sending the same update to a peer or peer group,
