Different types of L2VPN include Ethernet VPN (EVPN), Virtual Private LAN Service (VPLS), and Layer 2 Tunneling Protocol (L2TP).

• Ethernet VPN (EVPN) - Uses BGP as the control plane protocol for distributing MAC addresses across the network.

• Virtual Private LAN Service (VPLS) - Extends a LAN over the network, allowing multiple sites to appear as if they are on the same LAN segment.

• Layer 2 Tunneling Protocol (L2TP) - Creates a tunnel between two endpoints to transport Layer 2 tra...read more
