Re: RIP Timers

I think you are a little bit confused with the timers

invalidate timer is when you didn't get a route update on a route that
is in your table for ~180 sec (that is the status you are in)
holdown timer is when suddenly you get a higher metric for an already
installed route (lets say you have 1.1.1.0/24 with metric of 2 and
suddenly you get that route with a metric of 3 then your router will
start to count the hold down timer)

between the invalidate and the flash timer if you receive an update
for your route with a better metric your router immediately update the
routing table and that is exactly what happened in your scenario

hope that sort your mind a Little
