All, Xspedius (formerly e.spire/ACSI) is in the process of converting BGP connections to MD5. We have already done so with both of our transit providers and we're working on contacting customers that we do BGP with. If anyone is a customer of Xspedius and wants to convert to MD5, please email me or open a ticket with the NOC and request that it be referred to Dwayne Chin in Tier II DMC, who is working with me on this project. Otherwise, we will be contacting you directly.

Based on the ticket we filed last week, Managment does not feel its warranted to make these changes. On the other hand, SPRINT was willing and able to take MD5 session info right away.

Perhaps we are all making too much of this...

It appears that Winstar feels that there is no need for MD5 authentication of peering sessions. One of our customers has just had the following response from Winstar following a request to implement MD5 on their OC3 connection to Winstar. My first suggestion is to locate another upstream provider (they have 3 already).

However, perhaps someone from Winstar would care to help us all understand what the alternative solution is to securing the session via MD5? I would *love* an alternative to the 5 days of work we've just gone through.

xxxxx,

Winstar does not currently run MD5 authentication with our peers.
