I got this to work in Packet Tracer 5.1 but I just cant seem to figure out what is going on in my home lab.
Router A: (2501 Version 11.1(18 ))
Runs RIPv2
Advertises network
192.168.1.0/24
timers basic 900 180 180 240 (update, invalid, hold, flush)
Router B: (1721 Version 12.3(2)T8 )
Runs RIPv2
Advertises network
192.168.2.0/24
timers basic 30 20 20 30
All I am doing is simply trying to observe a route become invalid and be flushed from the routing table. Router B should receive an update from router A every 900 seconds. But the route will become invalid 20 seconds after receives the update and be flushed 30 seconds after that. It worked for me in packet tracer 5.1 but when I do it in my home lab it takes minutes for the route to get flushed. I must be doing something wrong. I just cannot figure out what. Any ideas?

First thing, if the IOS is asking you to enter the timers on RouterA, you are entering 900 seconds for updates to be sent, 900 seconds / 60 seconds (equals 1 minute ) = 15 minutes. This would mean that RouterA is only sending updates every 15 minutes. The other is every 30 seconds, which is default for RIP. Try setting RouterA back to the default timer settings.
