VPP/OVN
From fd.io
Project HotDog
Introduction
Integration of OVN and VPP. The initial phase is to integrate VPP as a VTEP gateway to OVN. There will be a simple agent written in Python that uses the VTEP OVSDB database on one side and programs the VPP data-plane on the other.
If a packet against all odds does reach VPP (after having been ping-ponged between <n> tables in some openflow setup with a raft of ARP/ND layer violating proxies), VPP will forward the packet onto a VXLAN or Geneve tunnel. Or through a NAT? Or direct if this is IPv6? Of course none of these solutions support IPv6 yet.
Work list
- Integration bridge. Create the integration bridge and add the physical interface(s) that is used for logical network connectivity. Done outside of the ovn-gateway-vpp?
- On agent init: Register VPP as a Physical_Switch entry in the VTEP database, update rows with ports and tunnels
Testing
Integration tests will be achieved by extending the existing testing tool coming with ovs/ovn (make check TESTSUITEFLAGS='-k ovn'). Specific tests cases will be built for that purpose.
