good catch - looks like a simple typo to me, probably with the interface addresses, all other things being equal > 2)summariztion Q > > area 1 has these subnets > > 192.168.1.0/24 > 192.168.2.0/24 > 192.168.3.0/24 > 192.168.4.0/22 > > summerie like this > > area 1 range 192.168.2.0 255.255.254.0 > area 1 range 192.168.4.0 255.255.248.0 > > What happends to 192.168.1.0 ..... shouldn`t that be in the area range > command.....sorry....i seem to be missing something major.... > no... because there's no way to summarize 192.168.1.0/24 without including 192.168.0.0/24. I mean, what other sub-networks do you want to summarize with 192.168.1.0? Think about it for a minute (hint - summarization occurs most logically at EVEN sub-network boundaries...192.168.1.0 is an odd /24 boundary) > > many thanks in advance.. > > > steve > > > _________________________________________________________________ > Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp _________________________________________________________ Do You Yahoo!?
