Re: Are these Contiguous Networks?
Auto-summarisation only occurs at a classful network boundary. So in the above topology, all of the networks are a derivative of the classful network 10.0.0.0/8 (class A). No auto-summarisation would occur. The network becomes discontiguous when you have to cross over another network to get to an address in the same… -
Re: Are these Contiguous Networks?
The network IS contiguous, as there is only ONE classful network. A discontiguous network is as I defined in my previous post. The key to this is understanding what auto summarisation does, and where it does it. Auto summarisation will automatically summarise a subnet back to it's classful network, AT A CLASSFUL NETWORK… -
Re: Are these Contiguous Networks?
Well the 10.25.67.64/27 network will only be correctly advertised to Router C if you turn of auto-summarization for RIPv2. IF not it will be advertised as 10.0.0.0/8. RIPv1 does NOT support discontinuous networks. This means in the above topology, you would run into problems, because all the networks will be seen as… -

Re: Are these Contiguous Networks?
Hello Frank, I think you are totally wrong if you think the network I posted above in my first post is a discontiguous network. As correctly pointed by Network Veteran ,it is a contiguous network and please dont confuse me anymore. I hoped NetworkVeteran would reply but he didn't. Instead most of you gave incorrect answers… -
Re: Are these Contiguous Networks?
Thanks for the clarification. :) ***EDIT*** @NetworkVeteran So if I am understanding you correctly, in urvi's example if the 10.82.113.0 /30 had been instead a 11.82.113.0 /30 it would then be considered discontiguous as we would have a different major network, due to the change in the /8 section of the network. My mistake… -

Re: Are these Contiguous Networks?
Thanks NetworkVeteran! But I have one last question- Does this mean that 10.25.67.64/27 will also be advertised to Router C in the above case? 2ndly,the link you provided implies that RIPv1 don't support discontiguous networks but does RIPv2 support discontiguous networks? Also RIPv1 does support contiguous like RIPv2? I'm…
