RIP: received v2 update from 192.168.1.11 on Serial0 RIP: received v2 update from 192.168.1.129 on Ethernet0 RIP: ignored v2 packet from 10.1.1.1 (sourced from one of our addresses) Since I don't have PPP setup, I'm guessing the RIP advertisements are being dropped and routers 2 and 3 simply have nothing to advertise to or receiv from. I have not configured encapsulation or any of that. I am getting the sneaking suspicion that this has everything to do with my serial hub and spoke setup. Routers 2 and 3 which are spokes from R1 are not sending or receiving any RIP updates. It is sending and receiving in version 2. I am however ignoring the advertisement for the loopback on R1. ![]() Both are directly connected, but I am not receiving any advertisements from the othe loopbacks. I ran a debug ip rip on R1 and found that the advertisements are being sent across my serial connections. ![]() I have added those statements and still cannot ping.

I thought at first this was because I wasn't using the no auto-summarization statement, but i have added that and it is still changing the network back to 10.0.0.0. The problem I can't understand at the moment is in my router rip statement: it is changing 10.1.1.0 to 10.0.0.0. All of my ethernet and serial interafces using the 192.168.1.0 spaces are able to ping fine to and from each router. I have added the networks to my router rip satements, networks 192.168.1.0 and 10.1.1.0. I have 3 routers, each connected through ethernet and serial, and each with a loopback interface using a /29 mask and the ips 10.1.1.1-3. Hi, I am having some difficulty understanding a setback I'm experiencing with RIP version 2 advertising and a loopback design.
