Question:
Refer to the exhibit. After a RIP route is marked invalid on Router_1, how much time will elapse before that route is removed from the routing table?
- 30 seconds
- 60 seconds
- 90 seconds
- 180 seconds
- 240 seconds
Explanation: What you need to read up on is around the Count to infinity routing loops, the holddown timers are used to ensure that routing loops dont occur and the hold down timer only occurs after 180s then at 240s the bad route is flushed/deleted. Coming back to the question where it asks for the time elapsed before it gets removed. So once the holddown timer passes thats when it knows there is a bad route, then the question is asking how long does it stay in the routing table before it gets “flushed” so that is 240-180=60s
