VXLAN+VLAN+BRIDGE+LINUX

• Both Host A and Host B are running Linux with identical VXLAN and VLAN aware bridge configurations.
• They communicate through a VXLAN overlay (ID 100) carried over multicast (239.1.1.1) on UDP port 4789.
• VLANs are extended across the VXLAN tunnel.
• Subinterfaces br0.10 and br0.20 provide access to specific VLAN networks (10 and 20).
• Devices on the same VLAN across hosts can directly communicate as if they are on the same Layer 2 segment.

Use iproute2 tools (testing)
