Jim,
Several things for neighbors. MTU must match. So on the Cat1 interface interface VLANX ip mtu 1500 or system mtu 1500 (and reboot) subnet mask must match on the two, double check it use show ip ospf interface brief make sure both are in the same area. Make sure neither of them (or both of them) have the stub flag set area X stub or area X nssa So the 4 things that must match are MTU subnet mask Area Stub Flag Regards, Tyson Scott - CCIE #13513 R&S, Security, and SP Managing Partner / Sr. Instructor - IPexpert, Inc.

I even took off the keys, defined a neighbor etc. Is there something needed to make this work? Thank you, JT
