Hi
Given that there are OVS1 and OVS2, two VXLAN between these,
VXLAN1000 and VXLAN2000 belong to same Bridge.
OVS1 send a packet through VXLAN1000, then VXLAN2000 of OVS2 will forward it
once VXLAN1000 receive the packet.
So OVS1 will also receive the packet, next VXLAN1000 of OVS1 send it again.
The packet will continuously send between OVSs.
OVS1:
Bridge br2
Port "vxlan2000"
Interface "vxlan2000"
type: vxlan
options: {key="2000", remote_ip="2.2.2.1"}
Port "vxlan1000"
Interface "vxlan1000"
type: vxlan
options: {key="1000", remote_ip="1.1.1.1"}
Port br2
Interface br2
type: internal
OVS2:
Bridge br2
Port "vxlan2000"
Interface "vxlan2000"
type: vxlan
options: {key="2000", remote_ip="2.2.2.2"}
Port "vxlan1000"
Interface "vxlan1000"
type: vxlan
options: {key="1000", remote_ip="1.1.1.2"}
Port br2
Interface br2
type: internal

These are just ports that will receive a given VNI. Once the packet
is received, the ports are bridged together.
