Thanks for the response. That is exactly my question, i.e. when I use the classful network, e.g. 192.168.x.0, then it works, however, when I summarise it to 192.0.0.0, then it does not. RIP v2 supporting classless routing, *should it not have been able to* propogate summarised networks? Or what am I missing here?
RIP is behaving correctly. 192.168.x.0 IS the correct bit boundary to summarize on, and 192.0.0.0 isn't. All it knows how to do by itself is boundary summarization.
You can always add an ip summary address rip to your advertising interface, and whatever major boundary you'd like, and it will do it. But it still has to fall on a major boundary that the contributors can be summarized together into (it isn't arbitrary, like an acl for example).
You don't summarize when enabling RIP on an interface (that's what the network command does).
If you want this router to advertise 192.0.0.0/8 instead of every single loopback address, you need to use ip summary-address rip 192.0.0.0 255.0.0.0 on the interface facing the RIP routers. However, you must first enable RIP on those interfaces by entering the network command (with classful boundary) or using the redistribute command as explained before.
