Looks like a wacky router. A packet capture here would be helpful, or a debug
of LSA's (sorry, my cisco command memory is lacking these days) Type 4's are o
nly generated by ABR's so it would seem that your 3.3 router would be the most
likely candidate, however if strange things are happening, you can't rule too m
uch out. Can you disconnect the connection into the backbone and see if the pr
oblem persists or is this a production network? (during a time when you are rec
ieving this error)
