1. I took off the redist IGRP to try to stop the bri circuit flapping
2. The only routes that I had redistributed into ospf from igrp were the
routes that igrp generated from R4
3. I did the same thing on the EIGRP (R2) side.
this thing is really just ugly. the one thing that i do notice is that
whenever the isdn circuit comes up, all my ospf routes get re-aged... so i
get no routes older than 120 seconds.
