Application Scenarios for L2TPv3

Application Scenarios for L2TPv3

An enterprise has branches located in different cities. The branches deploy Ethernet networks and have gateways to allow access to the IP network. To establish Layer 2 connections between the branches as well as between the headquarters and branches, L2TPv3 can be enabled on the gateways. The gateways then become L2TP Control Connection Endpoints (LCCEs) and set up L2TPv3 tunnels to transparently transmit Ethernet packets, lowering carrier network investment.


L2TPv3 can be used to set up point-to-point (LAC-LAC) connections, but not point-to-multipoint connections.

L2TPv3 can be used only when the devices at both end of the tunnel connect to VLANs or use AC interfaces.

Only one VLAN can be configured for an L2TPv3 tunnel.
