BGP over TLS

Mon Oct 21 18:42:18 UTC 2019

The article linked says no mainstream BGP implementation supports TCP-AO.
IOS-XE and IOS-XR support it.

While I do not represent the Cisco view, personally I like the idea of BGP over TLS.

At least for those systems that run on Linux (which is most all of the
major's except Juniper) I suspect if we went to the relevant kernel folk
with a clear plan on how handling TCP-MD5 in a way that would make
transitions much easier they'd listen.

The troll response at the top of my post was actually based on a
response from one of the kernel folk, who dislike TCP options even more
than network operators.

If anyone is at all interested in this I'm happy to discuss and flesh
out anything that's not clear. After I wrote this (over a few bottles of
red on the flight to linux.conf.au this year) I sent it to a bunch of
people that had expressed interest, including a few BGP implementations,
but nobody bit.
