Yep, that's one of the solutions... You can also summarize that network
with the 'summary-address' command and redistributing connected... Or
another way is to use an ip default-network. The problem you're having with
using a default-network is that it needs to be an IGRP system route, not an
internal. Meaning, a different classful network. So if you are using
170.100.0.0/24 networks, you would need a 170.200.0.0 route in IGRP which
can then be the default...
