L2TP Ñ Virtual Dial-Up Configuration (L2TP)
The following L2TP commands allow you to add, delete, and modify tunnels. L2TP router information that can be
conÞgured includes:
¥ Names
¥ Security authentication protocols and passwords
¥ Addresses
¥ Management of trafÞc performance
Note: Two remote commands speciÞc to L2TP are also included in this section.
L2TP ?
Lists the supported keywords.
L2TP ADD
Creates a tunnel entry.
L2TP SET ADDRESS
Used to deÞne the IP address of the other end of the tunnel, either the remote L2TP Access Concentrator (LAC) or
remote L2TP Network Server (LNS).
Caution: If the IP address of the remote tunnel is part of a subnet that is also reached through the tunnel, a routing
table entry for this address must be explicitly added. Normally, this routing entry will be added to remote entry,
which has the default route.
Note 1: When a remote router tries to create a tunnel, the remote routerÕs IP address is not authenticated .
Note 2: If this command is not used, then <ipaddr> defaults to 0.0.0.0, and this end cannot initiate the tunnel.
