Hi all, I have just been reading up about ospf, what I want to know is, If a have a router that is summarised to advertise the 192.168.0.0 network, and the router at the other end sees this, If I then put another router at another site and advertise the 192.168.1.0 network, will it be routed correctly, as routers should use the longest match criteria ?
that will not work, because those two networks overlap. One router is advertising 192.168.0.0 and the other is advertising 192.168.1.0. The first router already has 192.168.1.0 included in its summarized address space.
you might be able to get it to work with static routes but you are talking about using dynamic routing protocol in your first post. Your first router is saying, everything belonging to 192.168.0.0 255.255.0.0 is behind me, and then if you add a router saying 192.168.1.0 255.255.255.0 is behind me.....that won't work. they overlap.
explain your topology, maybe i am missing something.
By default, summary LSAs are not summarized so you would need to provide the mask information to get a proper answer.
If you're asking about classful addressing then those two networks do not overlap. One router is advertising 192.168.0.0. This is a class C network so the summary is 192.168.0.0/24. The other router is advertising 192.168.1.0. The the summary for this network is 192.168.1.0/24. These are two completely different networks and that would work.
