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 > > > On 2019-11-25 03:43, madhava gaikwad via freebsd-net wrote: > > 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. > > _______________________________________________ > > freebsd-net@freebsd.org mailing list > > https://lists.freebsd.org/mailman/listinfo/freebsd-net > > To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org" > _______________________________________________ > freebsd-net@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-net > To unsubscribe, send any mail to "freebsd-net-unsubscribe@freebsd.org" > > -- Rod Grimes rgrimes@freebsd.org
