From my side, With or without the IETF – I will continue to use CRH and we will continue to make product choices based on it. CRH is not SRv6 – it is, and we have stated this before, a building block for many things.
In our case – the ability to steer traffic is what drives a lot of what we do, but at the same time – the destination option SID for 16/32 bit which is an arbitrary number we can tie to functional behavior on the server side – is useful. I also point out that as I said time and again, we could not wait for the IETF, and we have invested significantly in CRH development into various products – and the rejection of CRH by the IETF – by a DT inside SPRING when the document is actually in 6man and is not srv6 – will simply lead to a case of us making large purchasing decisions on the vendors that choose to support what would be a proprietary protocol. So – rather than contributing to open standards the IETF by choosing one option – an option favored in the DT report – where 5 outta 7 members were actually authors or directly related to CSID – the IETF will be contributing towards what will become a proprietary protocol – either on IANA allocated code points, experimental code points or squatted code points – either way – CRH will continue and we will base our millions a year in purchasing partially on this factor (especially considering the significant amount of development resource that has been put into this – and yes – people will say – why did you put the resources into it – well – CRH has been stable in RFC since before CSID existed – and development cannot stop because of inertia in the IETF) CRH is functional – in production – and deployed – and caters for use cases simply not covered by CSID – because they have entirely different purposes. CSID was built to compress SRv6 – CRH is a building block for whatever the hell you want it to be. To choose one over the other disregards this entirely. Hence, I say this again, I am supportive of moving multiple options forward here – one within spring, and the other in 6man where it currently resides, to cater for disparate use cases.

As a vendor, we do hope to pick one solution to be standardized, to facilitate the network deployment. Also, since the CSID has been implemented by many vendors, I will suggest to adopt CSID.
