I've just been learning about classless/classful routing and here's what
we've come up with.
Classless routing just routes via ip address without the mask. Classful
routing routes with ip addresses and subnet masks.
Classless routing is OSPF, EIGRP. RIPv2, IS-IS, and BGP-4. They require the
same subnet on ALL routes propagated through them. They also allow
auto-summarization due to being on the same subnet.
Classful routing is IGRP, and RIPv1, which allows routing across multiple
class networks (A,B,C) or multiple subnets. This is possible due to the
inclusion of subnet masks in the routing tables.
I think I've left out something, but offhand on a Friday night I just don't
remember.
