SR-MPLS utilizes IPv4 data plane and and can service v4 v6 edges  6to4
softwire mesh framework from the VPN overlay aspect.

Can SR-MPLS use IPV6 data plane?

Reason why I am asking is that it is very simple to get from LDPv4 core to
SR-MPLS core.

However if you have an existing brown field SP core and your end goal is to
get to SRv6 - how can you easily get there.

So my thoughts are you can use SR-MPLS as a stepping stone so to speak to
get to SRv6.

To that end you could use Greg Mirsky draft of tunneling SR-MPLS in SRV6
interoperability and use other inter operability drafts.

But let’s say you prefer to get from point A go point B seamlessly and
native naturally without any translation.

An analogy would be migratory to IPV6 instead of using translation
technology tunnels you dual stand the entire network and use ds-lite or LSN
or 6RD to close the gap.

So my thoughts on getting to the “end state” SRv6 are we follows:

MPLS LDPv4

MPLS LDPv6

SR-MPLS v6

Once you have a v6 core and you have decommissioned LDPv6 you now have the
v6 data plan ready to go to get to SRv6

SRv6

Only caveat with this idea is I am not sure if SR-MPLS supports IPv6 data
plane v6 label binding.


Kind Regards
