Badger,
When you redistribute connected do you limit it to just the loop 0 address
through a route-map or do you just do a general redistribute connected?
Thanks,
JDC

Still no response to my question. Bottom line is that whenever I'm doing
mutual redistribution and throw the "redistribute connected" under with
eigrp or ospf, their actual connect routes are dropped from redistribution.
This is driving me nuts, is my question that bad?
