hi every body ,
i have configured this network topology using boson software and RIP V1 routing protocol with following settings:
1) pc#1 has this subnet 192.168.1.16/28
2) pc#2 has this subnet 192.168.1.32/28
3) pc#3 has this subnet 192.168.1.48/28
4) pc#4 has this subnet 192.168.1.64/28
the network between router A and B is subnet 192.168.1.0/25
the network between router B and C is subnet 192.168.1.128/25
5) pc#11 has this subnet 192.168.1.144/28
6) pc#12 has this subnet 192.168.1.160/28
7) pc#13 has this subnet 192.168.1.176/28
8) pc#14 has this subnet 192.168.1.192/28
as I know this topology doesn't work with RIP v1 but in my lab it worked....
I believe that we are finally describing things in the same way in this discussion and you are exactly correct.
In several of your posts you phrase the question in terms of the subnets on PCs. And I have said several times that it does not matter what is configured on PCs but matters what is on router interfaces. It was not clear to me in your original picture whether each PC was connected to a unique interface or whether the PCs shared a common interface. From the continuing discussion I recognize that you were using them as each PC connected to a unique interface with a corresponding subnet. Now that I understand this I completely agree with you that it would not work on real routers running RIPv1 and that if it works in the virtual lab then it is a problem in the virtual lab.
