JUNOSe 11.1.x Broadband Access Configuration Guide
When you configure any of these AVP types for relay in an L2TP tunnel-switched
network, the router preserves the value of an incoming AVP of this type when packets
are switched between the inbound LNS session and the outbound LAC session.

Configuration Tasks

To configure and use an L2TP tunnel switch profile in an L2TP tunnel-switched
network:
1.
2.
3.
The following sections describe how to perform each of these tasks.

Enabling Tunnel Switching on the Router

To enable L2TP tunnel switching on the router, use the l2tp tunnel-switching
command. By default, tunnel switching is disabled.
For more information, see "Enabling Tunnel Switching" on page 384.

Configuring L2TP Tunnel Switch Profiles

To configure an L2TP tunnel switch profile:

Configuring L2TP Tunnel Switch Profiles
Ensure that L2TP tunnel switching is enabled on the router.
Configure the L2TP tunnel switch profile.
Apply the L2TP tunnel switch profile to the tunnel in one of the following ways:
To apply a named tunnel switch profile through an AAA domain map, use
the switch-profile command from Domain Map Tunnel Configuration mode.
For details, see "Applying L2TP Tunnel Switch Profiles by Using AAA Domain
Maps" on page 397 .
To apply a named tunnel switch profile through an AAA tunnel group, use
the switch-profile command from Tunnel Group Tunnel Configuration mode.
For details, see "Applying L2TP Tunnel Switch Profiles by Using AAA Tunnel
Groups" on page 398 .
To apply a named tunnel switch profile through RADIUS, include the
Tunnel-Switch-Profile RADIUS attribute (VSA 26-91) in RADIUS Access-Accept
messages. For details, see "Applying L2TP Tunnel Switch Profiles by Using
RADIUS" on page 399 .
To apply a default tunnel switch profile to a virtual router, use the aaa tunnel
switch-profile command from Global Configuration mode. For details, see
"Applying Default L2TP Tunnel Switch Profiles" on page 399 .
To enable L2TP tunnel switching:
host1(config)#l2tp tunnel-switching
Create the L2TP tunnel switch profile and assign it a name. The l2tp
switch-profile command accesses L2TP Tunnel Switch Profile Configuration
mode.
