Hey, no prob.. sure lets wait to hear back on the use case that could be interesting :)

Hi Rodney,

I haven't said that is not approved or an RFC exist (there are many and some 
interesting use cases) , but can you tell me of any in production deployments?
I can not, though for the SRH to be in its current state as a "Standards Track" 
document
there must be running code someplace... and that usually implies production 
deployments
as well, or atleast not small scale tests.

The conservatory still there, if you check with your customer, how many are 
willing to deploy it?
I did not mention any customer(s) at all, I stated I was interested in any use 
case.

Open for an offline talk about it as i really like to know if you are seeing 
other thing..
I do not know that there is much to talk about.

Best regards.

Hi Alex,

While I'm not a BSD developer, i really doubt it, considering that the
building blocks for SR are not there ( mpls support or just label
push/pop/swap).
He specifically stated SRv6 which is not MPLS based.
The building blocsk if one was to need this in a BSD are in
OpenBSD which has an MPLS implementation.

On the other hand, on SRv6 as you mentioned you rely on IPv6 headers and
there is a lot of conservatory about it.... ( unless you are a Cisco fan!)
:-)  The SRH is 5 years and 26 revisions into the process and has
been  "Submitted to IESG for Publication" per:
https://datatracker.ietf.org/doc/draft-ietf-6man-segment-routing-header/
so it should be possible for someone to do an implementation in FreeBSD

I'm interesting on the use case, if you don't mind... is it just service
chaining you application ? Usually servers are just part of an overlay (
call it VXLAN,? MPLS? or something over something else...)
I would be interested to here the use cases as well.

Best regards.

Santiago

Hello Experts,
I want to know if there is any effort/planning going on to implement Segment 
Routing (RFC 8402?https://tools.ietf.org/html/rfc8402). I see Linux supporting 
it. Wondering if there is something planned on FreeBSD too.My app runs on 
FreeBSD and I have a use case to share information from one application gateway 
to another about connection identity. I thought SRv6 header can help me here.
Thank you.Alex.
