Important:
The configuration of RADIUS-based subscriber profiles is not discussed in this document. Please
refer to the documentation supplied with your RADIUS server for further information.
Important:
This section provides the minimum instruction set for configuring local subscriber profile for L2TP
support on the system. For more information on commands that configure additional parameters and options, refer to the
LAC Service Configuration Mode Commands
chapter in the
Command Line Interface Reference
.
To configure the system to provide L2TP support to subscribers:
Step 1
Configure the “Local” subscriber with L2TP tunnel parameters and the load balancing parameters with action by
applying the example configuration in the
Configuring Local Subscriber
section.
Step 2
Verify your L2TP configuration by following the steps in the
Verifying the L2TP Configuration
section.
Step 3
Save your configuration to flash memory, an external memory device, and/or a network location using the Exec mode
command
save configuration
. For additional information on how to verify and save configuration files, refer to the
System Administration Guide
and the
Command Line Interface Reference
.
Configuring Local Subscriber
Use the following example to configure the Local subscriber with L2TP tunnel parameters. Optionally you can
configure load balancing between multiple LNS servers:
configure
context <
ctxt_name
> [-noconfirm]
subscriber name <
subs_name
>
tunnel l2tp peer-address <
lns_ip_address
> [ preference <
integer
> | [ encrypted ]
secret <
secret_string
> | tunnel-context <
context_name
> | local-address <
local_ip_address
>
}
load-balancing { random | balanced | prioritized }
end
Notes:
<
ctxt_name
> is the system context in which you wish to configure the subscriber profile.
<
lns_ip_address
> is the IP address of LNS server node and <
local_ip_address
> is the IP address of
system which is bound to LAC service.
Verifying the L2TP Configuration
These instructions are used to verify the L2TP configuration.
Step 1
Verify that your L2TP configurations were configured properly by entering the following command in Exec Mode in
specific context:
