L2TP configuration
Overview
The NFM-P supports the configuration and management of L2TP sites, tunnel group profiles, and tunnel profiles. L2TPv2 and L2TPv3 tunnels are available. Both can be configured at the same time.
A typical L2TPv2 configuration is applied to two NEs; one NE performs the LAC role and the other NE performs the LNS role. An NE can perform both LAC and LNS roles. At least one ISA-LNS group must be configured for the LNS NE. See Working with ISA-LNS groups for information about ISA-LNS groups. See To configure an ISA-LNS group for information about creating and configuring an ISA-LNS group member.
L2TPv3 tunnels pass Ethernet traffic. The tunnels are symmetric and do not have LAC and LNS ends.
Note: An NE must be in chassis mode B or higher to support L2TP.
You can also enable L2TP on a VPRN site. See Chapter 79, VPRN service management .
The following procedures describe how to configure L2TP.
