Explanation

In RIP, when a directly connected network goes down, the router immediately sends triggered updates to its directly connected neighbors containing the withdrawn route. This is a rapid convergence mechanism - unlike regular periodic updates, triggered updates happen immediately to propagate topology changes faster through the network.
