Operation of distance vector (2/4) • Periodic Updates are sent at regular intervals (30 seconds for RIP and 90 seconds for IGRP). – Even if the topology has not changed in several days, periodic updates continue to be sent to all neighbors. – Neighbors are routers that share a link and are configur ...
