my soho is now an ospf network...

how?
went to router 3 and added ospf (router ospf 3, the 2 networks)
same to router 2 and added the 2 directly connected networks,
then router 1 and it's 4 directly connected networks,
then went back and whacked eigrp on each router,
hopped over to the 3550, added ospf and it's directly conected networks, whacked eigrp, and
now everybody is pinging everybody...

took about 5 minutes...
