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!) 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...) Best regards.

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"
