Hi Ron,
You still do not name segment types in this version of the draft. * You called them "loose" and "strict" in your email [1]. * In previous versions you called them "Prefix SID" and "Adjacency" [2] and in your ISIS draft [3]. It seems clear to anyone that knows and understands Spring work; these are the same fundamental Segment Routing Prefix and Adjacency SIDs [4]. It seems clear that you are trying to package what is essentially a RH that is based on Spring work as something else - but it comes through obviously in the draft. Changing names, removing references and avoiding their identification does not change the sole use of CRH. https://tools.ietf.org/html/draft-bonica-6man-comp-rtg-hdr-22#section-4 has: Each CRH-FIB entry contains: o A IPv6 address. o A forwarding method. KT> This is nothing but a function/behavior in SRv6. In case of SR-MPLS, it would map to Prefix, Adjacency and Binding SID instructions. o Method-specific parameters (optional). KT> This is same as arguments or context Further on The forwarding method specifies how the processing node will forward the packet to the next segment endpoint. The following are examples: o Forward the packet to the next-hop along the least-cost path to the next segment endpoint. KT> Exactly the definition of Prefix SID o Forward the packet through a specified interface to the next segment endpoint. KT> Exactly the Adjacency SID. Some forwarding methods require method-specific parameters. For example, a forwarding method might require a parameter that identifies the interface through which the packet should be forwarded. KT> It is clear you mean to introduce more such "methods" - this is nothing but the other Spring Segment ID types and their associated instructions. The change done in https://tools.ietf.org/html/draft-bonica-6man-comp-rtg-hdr-22#section-5 processing rules says : o Submit the packet and optional parameters to the IPv6 module. Optional parameters are derived from the CRH-SID. See NOTE. NOTE: By default, the IPv6 module determines the next-hop and forwards the packet. However, optional parameters may ellicit another behavior. For example, if a next-hop is provided as an optional parameter, the IPv6 module forwards to that next-hop. KT> How is this not exactly like the different instructions/behaviors specified in Spring. It is clear that this work is associated with and leverages the Spring architecture. The original motivation for this work was for bringing compression efficiency (which is being worked on in Spring). No amount of removal of references and taking things out of this draft will change its original and still intended purpose. A leopard cannot change its spots! Adoption call for this draft in 6man WG without the compression discussion in Spring WG will be going against the decisions that we've heard in the past about how the Spring and 6man WGs are going to collaborate.
