R1 won't do anything if you disconnect its fa0/0 interface. Due to split horizon and the fact that it's the only interface configured, it doesn't have anyone to update.
Also, R2 probably doesn't notice a problem. I bet its Ethernet interface on that side is still up. (If you were using serial, this wouldn't be the case. A serial interface notices when the other side goes down, but Ethernet might not, depending on the physical layer you're using. How are R1 and R2 connected, by the way?) Here's what you need to do: Configure R1's other Ethernet port (fa0/1) with an address from another network. Be sure to add that network to R1's RIP statement. Now use that fa0/1 interface in your test. Shut it down. That will cause R1 to send a triggered update out its fa0/0 interface (hopefully) and cause R2 and R3 to put the route into holddown. Hope that makes sense. Let us know if it works! Thanks. Priscilla At 05:17 PM 3/6/02, Jerry P. wrote: >Hi Priscilla: > >Here are the configs.
