I have a little confusion in the understanding of RIP timers.
First the basics... update timer is 30 secs --> Invalid timers should be 3 times of update i.e 90secs but the default is 180secs --> Holddown timers should be 3 times of update i.e, 90secs but the default is 180secs --> Flush timer, default is 240 secs. Now there are three parts to my question... The first question might sound silly but for the sake of a clear understanding I'll write it. 1. Does the RIP updates timers work is series? i.e after one elapses the other starts? ex: once U-30sec is over --> Invalid starts and runs for 180 secs --> Holddown starts and runs for another 180secs --> And finally flush timer starts and runs for 240secs. Here the total time would be 30+180+180+240=630secs until a route is flushed out which is looking quite unreasonable! 2. Does the Invalid, Holddown & flush timers work is parallel? ex: once U-30sec is over -> Invalid, Holddown runs for 180secs along with the flushtimer which runs for 240secs? Here the total time would be 30+240=270secs until a route is flushed out which looks very much acceptable. 3. And why does the Invalid & Holddown timers run in parallel, if all they do? Because at the end of these two timers (IT & HDT) it would take another 60secs for flush timer to flush out the route, which means that all the timers IT/HDT/FT are kicking off at the same time immediately after update timer expires! I think I'm just complicating what is supposed to be a simple understanding!!! -RS _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
