This patchset provides support for the SRv6 End.DT4 behavior.
The SRv6 End.DT4 is used to implement multi-tenant IPv4 L3 VPN. It decapsulates the received packets and performs IPv4 routing lookup in the routing table of the tenant. The SRv6 End.DT4 Linux implementation leverages a VRF device. The SRv6 End.DT4 is defined in the SRv6 Network Programming [1].
- Patch 1/5 is needed to solve a pre-existing issue with tunneled packets when a sniffer is attached;
- Patch 2/5 improves the management of the seg6local attributes used by the SRv6 behaviors;
- Patch 3/5 introduces two callbacks used for customizing the creation/destruction of a SRv6 behavior;
- Patch 4/5 is the core patch that adds support for the SRv6 End.DT4 behavior;
- Patch 5/5 adds the selftest for SRv6 End.DT4 behavior.
I would like to thank David Ahern for his support during the development of this patch set.
Comments, suggestions and improvements are very welcome!
Thanks, Andrea Mayer
