L2TP Module Requirements

The supported modules for LNS depends on the type of E Series router that you have.

ERX7xx Models, ERX14xx Models, and the ERX310 Router

To use an LNS on ERX7xx models, ERX14xx models, and the ERX310 router, at least
one Service line module (SM) or a module that supports the use of shared tunnel-server
ports must be installed in the ERX router. For information about installing modules
in the ERX router, see the ERX Hardware Guide.
SMs provide dedicated tunnel-server ports that are always configured on the module.
Unlike other line modules, SMs do not pair with corresponding I/O modules that
contain ingress and egress ports. Instead, they receive data from and transmit data
to other line modules with access to ingress and egress ports on their own associated
I/O modules.
You can also create tunnels on E Series modules that support shared tunnel-server
ports. You can configure (provision) a shared tunnel-server port to use a portion of
the module's bandwidth to provide tunnel services. For a list of the modules that
support shared tunnel-server ports, see the ERX Module Guide.
For information about configuring tunnel services on dedicated and shared
tunnel-server ports, see the Managing Tunnel-Service and IPSec-Service Interfaces
chapter in JUNOSe Physical Layer Configuration Guide.
For information about line modules supported by the LAC and LNS and the type of
support each module type receives, see ERX Module Guide, Appendix A, Module
Protocol Support.
