I have always been a little confused by RIP & IGRP hold down timers.I wonder if some one could clarify the following. 1) Is the route marked as possibly down & placed into holddown only when a higher metric is received for the same route from the origional source? What if it receiced an update that a specific network was unreacable, but from a new source? 2)Once the route is is marked as possibly down and placed into hold down are packets still forwarded untill the route is flushed?
