EVPN for mobile transport

EVPN Overview for Mobile Networks

Ethernet VPN is a BGP-based control plane technology that provides multi-point Layer 2 and Layer 3 VPN services over an MPLS or VXLAN data plane. In mobile transport, EVPN replaces traditional VPLS by offering active-active multi-homing, MAC mobility, and integrated routing and bridging. EVPN uses MP-BGP with a new address family to distribute MAC and IP reachability information between Provider Edge routers. This allows cell site switches to participate in a virtual Ethernet broadcast domain spanning the transport network while maintaining control-plane-based learning instead of data-plane…
