Good to see this and this addresses the RFC 8200 issue – but yes, little bit more overhead if you include encapsulating IPv6 address and SRH with all the IPv6 SIDs. We have just published LSR-WG individual draft which significantly reduce the SRH overhead at least with NSPF-ID=4 (v6 SRH data plane). Check this out. https://www.ietf.org/internet-drafts/draft-ct-isis-nspfid-for-sr-paths-00.txt This would be presented in IS-IS (LSR) WG and/or SPRING. -- Uma C.
