After implementing:

• remote VTEP learning for logical switches (FDP-1385)
• FDB learning through L2 EVPN (FDP-1387)
• FDB advertising through L2 EVPN (FDP-1389)

An OVN logical switch configured with EVPN L2 support enabled (VNI and local IP set) should be able to setup VXLAN tunnels to remote vteps in the fabric and properly forward traffic from/to OVN workloads and the fabric.

Conceptually:

• the BGP control plane (FRR) should be running on the OVN Chassis (default namespace) where the workload resides
• the OVN workload should be connected (through a logical switch port) to an OVN logical switch that has L2 EVPN enabled (VNI and local IP set)

A multinode e2e test should be added to ensure that:

• ovn-controller properly detected all remote vteps that were learned (through BGP) from the fabric
• ovn-controller properly advertised to the fabric the L2 workload connected to the OVN logical switch
• traffic between the OVN workload and the fabric is correctly forwarded end-to-end
