metric holddown — router, IGRP
metric holddown no metric holddown
Keeps a route from being used for a given amount of time
This command tells IGRP to wait a specific time before implementing new routes. It helps you to avoid routing loops in networks that converge slowly by delaying routing updates. Routing loops are still possible, however, if all routers within the same IGRP domain are not configured the same way. Using this command can result in very slow convergence.
