quick summarization question

rakem

say i have 4 networks, with these IP addresses

192.168.0.1 /24
192.168.1.1 /24
192.168.2.1 /24
192.168.3.1 /24

these could be summarized as 192.168.0.0 255.255.252.0 right?

since this mask would allow for ranges from 192.168.0.0 to 192.168.4.0

hence the command i could use to manually summarize these would be:

ip summary-address eigrp 10 192.168.0.0 255.255.252.0

The only thing I saw 'wrong' was the range....it should be from 192.168.0.0 to 192.168.3.255, not 192.168.4.0. 4.0 is a new network.

The reange would be 192.168.0.0 to 192.168.3.0 with that summary address, so that is correct.
