count to infinity

count to infinity: A loop that happens when a link in a network goes down and routers on the network update their routing tables with incorrect hop counts. For example, a loop can develop if the link to Router C goes down. Router B then advertises that the link is down and that it has no route to C. Because Router A has a route to C with a metric of 2, it responds to Router B and sends its link to C. Router B then updates its table to include a link with metric 3, and the routers continue to announce and update their links to C until they reach the number 16. This is a count to infinity.
