To that end, I am balloting no-obj but I support Alissa's DISCUSS. The following comments may help get clarity here as well. It seems to me that the MPLS variant relies on the security properties of MPLS but that the IPv6 variant can potentially route packets over the public Internet and relies on the HMAC defines in draft-ietf-6man-segment-routing-header to protect the SRH from modification. Is that correct? To that end, the various nodes in the system must all be within one domain but you can have an untrusted IPv6 path in between them. Is that correct? The HMAC doesn't seem to be mandatory? When we look at that other document should it be mandatory under some conditions? I had some trouble understanding the algorithm in S 3.1.2. Let me see if I can reconstruct the scenario. We have a list of i ranges, R(i) each of which is identified by L(Ri), N(Ri), so for instance, so for instance, we might have two ranges: R0 -> L=10, N=2 -> labels 10, 11 R1 -> L=20, N=3 -> labels 20, 21, 22 And then these are indexed by treating these as one contiguous array A = [10, 11, 20, 21, 22] and then label(X) = A(X). Is that right? Nit: I found a bunch of examples of "e.g.:". The correct form is "e.g., " _______________________________________________ spring mailing list [email protected] https://www.ietf.org/mailman/listinfo/spring
