Hi Rob,
A Class C supernetted as a /22 is nothing but a
summary of 4 contigeous Class C addresses. If you are
using /24 on IGRP side, I think you can redistribute
by breaking a /22 into 4 /24s.
For example;
172.16.20.0 /22 is the aggregate of
172.16.20.0 /24
172.16.21.0 /24
172.16.22.0 /24
172.16.23.0 /24.
So create 4 summaries in OSPF and redistribute into
IGRP.
Tell me if it worked.
Good luck,
Mohan.
