Hhhmmmmm......
RIPv1 offers the command [no] auto-summary as well. Haven't tried this one
out, but I will hazard a guess that it would be useful in situations where
one is subnetting a classful address, and did want the advertisements to go
out at the classful boundary. For example, if connected to another RIPv1
router which was using a different classful network, but subnetted the same
way.
i.e. E0 = 192.168.1.1/28, S0 = 192.168.1.17/28 and S1 = 192.168.1.33/26 the
no auto command would prevent the advertisements from becoming
192.168.1.0/24
don't have access to routers at the moment, but I am open to correction.
I'll maybe take a look tomorrow. I do recall a phenomenon like this when
working on an IGRP lab one time. I'll have to dig out my notes.

RIPv2 also supports discontinuous networks (no auto-summary) and the ability
to do summarization (ip summary-address rip).
