Should we design a rational cost-efficient solution, we should choose the lowest overhead and narrowest working keys.In the abstract, sure. But if you want a practical, deployable, production network, it's multi-dimensioned.
We have probably largely converged to the same place. Your vantage point sees practical offerings where IPIP may make more sense to you than MPLS, my vantage point definitely only implements the rich features I need in MPLS tunnels (RSVP-TE, L2 pseudowires, FRR, L3 MPLS VPN, all of which technically could be done of course with IPIPIP tunnels) And the theory we agree that less is more. ECMP appears to be your main pain point, the rich features are not relevant, and you mentioned commodity hardware being able to hash on IPIP. I feel this may be a very special case where HW can do IPIP hash but not MPLSIP hash. Out of curiosity, what is this hardware? Jericho can do MPLSIP, I know JNPR's pipeline offering, Paradise, can. Or perhaps it's not even that the underlaying hardware you have, cannot do, it's that the NOS you are being offered is so focused on your use-case, it doesn't do anything else reasonably, then of course that use-case is best by default. -- ++ytti
