I received 20 responses which isn't exactly overwhelming :-). All of the responses included usage information for eBGP-MD5 and a few provided information on MD5 for interior protocols. In addition to these 20 I also received a few more with commentary. Conclusion from these messages?
+ only 2 required their peers to use eBGP-MD5
+ many wanted to use it but peers either refused or didn't know how
+ some issues concerning whether this protects you from any "real" threat
So, there you have it. Below are the breakouts and miscellaneous remarks that were included in the email I received. Thanks to all of you who took the time to send me something.
