SRv6 End.DT46 Behavior is defined in the IETF RFC 8986 [1] along with SRv6 End.DT4 and End.DT6 Behaviors.
The proposed End.DT46 implementation is meant to support the decapsulation of both IPv4 and IPv6 traffic coming from a *single* SRv6 tunnel. The SRv6 End.DT46 Behavior greatly simplifies the setup and operations of SRv6 VPNs in the Linux kernel.
- patch 1/2 is the core patch that adds support for the SRv6 End.DT46 Behavior;
- patch 2/2 adds the selftest for SRv6 End.DT46 Behavior.
The patch introducing the new SRv6 End.DT46 Behavior in iproute2 will follow shortly.
Comments, suggestions and improvements are very welcome as always!
Thanks, Andrea
