Interesting problem. Do these retransmissions correlate against any tcp window sizes?
TCP retransmissions would effectively be requested by the receiver through use of selective acks etc, so it implies that the segmentsd are either not reaching the destination or the acknowledgements are not reaching the sender properly.
If you have the time, I would set up a small file transfer first using ssh then ftp etc and capture at each interface in the path.
Time consuming, but you could then compare the tcp streams to isolate at which point the problem occurs.
There may be far simpler and helpful troubleshooting methods than mine that are posted however!
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
