Re: [bess] Last Call: <draft-ietf-bess-bgp-sdwan-usage-19.txt> (BGP Usage for SD-WAN Overlay Networks) to Informational RFC

[Linda Dunbar <[e-mail]>]

John,

There is a draft on BGP over TLS: https://datatracker.ietf.org/doc/draft-wirtgen-bgp-tls/
We are working with the author to enhance the draft.

We will add the reference to BGP over TLS. And remove the BGP over DTLS.

Can those changes address your comments?

Thank you,
Linda

I haven't done a full review of this document, but I did notice that Roman Danyliw balloted DISCUSS on version 15 [1], asking, among other things, "Are there pointers for BGP over DTLS? Over TLS?". This doesn't appear to have been addressed, either in Linda's reply to Roman [2], or in the text of the document. It seems ill-advised to be last calling a document with an unaddressed DISCUSS. For what it's worth, Roman's point seems to me to be on target - as far as I'm aware, there is no IETF specification for BGP over TLS, and I don't expect that there will ever be a specification for BGP over DTLS, given that BGP assumes a stream transport.

$0.02,

-John
