metric holddown — router, IGRP

Synopsis

metric holddown
no metric holddown

Configures

Keeps a route from being used for a given amount of time

Default

Disabled

Description

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.
