Wim SR-MPLS reuses the MPLS data plane. That is a nice brown field migration option for MPLS customers that want to eliminate ldp state. Don’t get me wrong SR-MPLS has its place and its for brown field MPLS deployments and SRv6 has its place as well for cases mostly intra domain where you don’t have inter domain traffic steering with very long strict paths which run into SR-TE MSD issues. For deployments that want to use the IPv6 data plane and have ubiquitous use cases inter or intra domain and not have the extra baggage 🧳 of SRv6 programming SID depth overhead with strict paths or SR-MPLS - MPLS data plane which also has MSD SID depth issue with long strict paths = CRH shines and is the best solution Thanks Gyan On Tue, May 26, 2020 at 10:27 AM Henderickx, Wim (Nokia - BE/Antwerp) < wim.henderickx@nokia.com> wrote: > if you look into the details RFC8663 from a data-plane operation is very > similar to CRH.
