I think this message is for Steve Shultz, and perhaps Kevin Thompson
of vBNS. We definitely are getting asymmetrical routing which is
cutting the data transfer rate down to unusable. It looks like
vBNS is handing traffic for 198.11.22 off to mci or eu.
The week of November 2, this was working perfectly.
Please help:
