Dear working group, as an operator I am currently working on getting SR-MPLS into a multi-AS, multi-service global core network. Managing a SID mapping for all relevant nodes and services has been done, but definitely was a serious effort in our environment as many different (company internal) parties need to be coordinated. SRv6 seems to me like a great opportunity for further network technology consolidation in the future, covering all kinds of network domains. This opportunity is, in my eyes, only based on the huge and universal address space offered by IPv6. Any continued or even additional need to map topological nodes or services to SIDs would, in my opinion, thwart the main opportunities of SRv6. In comparison to the relatively simple deployment of SR-MPLS in the mere core network, any end-to-end deployment of SRv6 throughout all core, aggregation and access network domains as well as data centers and service areas would require even more organizational units to agree on a new central SID registry. Thus I believe the many SRv6 use cases will only practically work when _not_ relying on new maps or tables for any kind of SID. Also the CRH does not solve a problem that I would consider as serious. From all scenarios we have seen so far and all research we have seen I seriously doubt that more than a few segments will be needed. And even if the number of segments needed came close to something like 10, I do _not_ consider the mere overhead of the SRH of 168 byte a serious problem. Overall I don't see how CRH solves more problems than SR-MPLS with a IPv6 control plane would do. And that would really be a less complex solution. I would truly prefer implementors to concentrate on everything that is need to complete use cases based on the plain SRH, rather than inventing a new routing header every other year. Thus I do _not_ support wg adoption of this draft.
