Just to update everyone on some of the strange traceroutes, MCI continues to support our customer relationship with BBN by taking MEDs, and will continue to do so for a bit longer, hopefully this will be transitioned real soon. BBN has been a great customer, best of luck in your new ventures! -scott Sean Kennedy <liam@bbnplanet.com> wrote on Mon, 17 Mar 1997

Just over two years ago BBN/NEARNET, BBN/BARRNet, and SURAnet (later BBN/SURAnet) independently selected MCI to provide Network Service Provider (NSP) transit services. The transit agreement obligated BBN-owned regionals to use MCI for transit services. Over the past two years BBN has migrated from this collection of semi-autonomous regional networks to one nationwide infrastructure. We have made minimal use of MCI transit services, using existing connections to MCI primarily to reach MCI customers.

In light of this change and in order to provide improved connectivity to their customers, BBN and MCI have agreed to replace the transit service agreement with a private peering agreement. Cessation of the transit agreement is scheduled for 3/31/97.

The technical impact of this change is that MCI will no longer announce BBN routes at the public interconnects, except to those providers who have purchased transit service from MCI. Providers with significant trans-national US infrastructure at DS3 or greater speeds who are reliant on MCI's announcement of AS1 prefixes are encouraged to pursue peering with BBN by contacting 'peering@bbnplanet.com' by 3/19/97. Those providers with a existing transit provider who peers with BBN should see no change in how they reach BBN customers (and should contact their transit provider with questions regarding its connectivity). Existing peers of BBN will see no change in our announcements or routing.
