Purpose
Selects the VPDN group and enters VPDN configuration
mode.
Enables the LNS to request L2TP tunnels for dialout calls.
Specifies the Layer 2 Tunnel Protocol (L2TP) that the VPDN
subgroup will use.
L2TP is the only protocol that supports dialout and IP
Note
TOS preservation.
Specifies the dialer profile pool or dialer rotary group to use to
dial out.
You can only configure one dialer profile pool or one
Note
dialer rotary group. Attempting to configure a second
dialer resource removes the first resource from the
configuration.
Returns to VPDN group mode.
Specifies the IP address of the LNS that is dialed out.
Optionally, you can configure the maximum number of
connections that can be made to the IP address and the priority
for the IP address (1 is the highest).
Specifies the local host name that the tunnel uses to identify
itself.
Configures the VPDN group to preserve the TOS field of L2TP
tunneled IP packets.
