Thanks for pointing out the error probability. I was looking
for this with the help of RFC 1071 just now.
I was getting virtually no CRC errors on the link, but a few giants.
Another reader of this list took the time out to write to me about
Layer 1 and 2 issues in this situation - something that was very
helpful for me (Thanks, you know who you are).
Meanwhile, we've nailed it down to this: whenever one of the 2 UUnet
T1 interfaces is shut down on *UUnet's end only* , things work fine.
As soon as it's configured up (if-no shutdown command), the corruption
occurs. This is independent from my side being shut down, unplugged,
or the circuit put into loopback from one side or the other.
CEF and their HSSI card have become prime suspects this way, I think.
Thanks,
bye,Kai
