Layer 2 VPN

Layer 2 VPN and Layer 2 Circuits over GRE / UDP with FTI Tunneling (ACX Series) — Use Layer 2 virtual private network (L2VPN) and Layer 2 circuit (L2CKT) services over generic routing encapsulation (GRE) and user datagram protocol (UDP) tunnels that use FTI tunneling. This configuration extends your Layer 2 domain across flexible IP-based networks. You can use existing CLI commands to configure these services.

[See Configuring Layer 2 Ethernet Services over GRE Tunnel Interfaces, Configuring Tunnel Interfaces on ACX Routers, and Configuring Flexible Tunnel Interfaces.]

Support for L2VPN and L2 circuit services over pseudowire interfaces (ACX7020-AC, ACX7020-DC, ACX7024, ACX7024X, ACX7100-32C, ACX7332, ACX7348, and ACX7509)—Use the PS interface to provision L2VPN and L2CKT services for unified Layer 2 connectivity across your infrastructure. This capability helps you extend customer segments, optimize resource utilization, and simplify service operations. Configure service instances and bind them to the PS interface, and specify encapsulation, VLAN membership, and CoS policies as required.
