Configuring an L2TP Tunnel

Configuring an L2TP Tunnel

An L2TP tunnel can be used to provide access services for enterprises, small ISPs, and the staff on business trips over a public network.


For details, see L2TP Protocol Configuration in the HUAWEI NetEngine40E Universal Service Router Configuration Guide - User Access.


The preference of the route from the LNS to the master LAC is higher than that of the route from the LNS to the backup LAC. The LNS will switch traffic to the route destined for the backup LAC only when a fault occurs on the network side of the master LAC.

In L2TP dual-device hot backup scenarios, if an L2TP tunnel is established on an L3VPN, URPF is configured on the LACs' network side, and the master LAC's access side fails, downstream traffic packets are discarded on the backup LAC.
