# Configure a static route so that packets destined for the PPP user will be forwarded through
the L2TP tunnel.
[LNS] ip route-static 10.2.0.0 16 192.168.0.10
2. Configure the LAC:
# Configure IP addresses for the interfaces. (Details not shown.)
# Enable L2TP.
<LAC> system-view
[LAC] l2tp enable
# Create L2TP group 1 in LAC mode.
[LAC] l2tp-group 1 mode lac
# Configure the local tunnel name as LAC, and specify the IP address of the tunnel peer (LNS).
[LAC-l2tp1] tunnel name LAC
[LAC-l2tp1] lns-ip 3.3.3.2
# Enable tunnel authentication, and configure the authentication key as aabbcc.
[LAC-l2tp1] tunnel authentication
[LAC-l2tp1] tunnel password simple aabbcc
[LAC-l2tp1] quit
# Create Virtual-PPP 1. Configure its username and password as vpdnuser and Hello and
PPP authentication as PAP.
[LAC] interface virtual-ppp 1
[LAC-Virtual-PPP1] ip address ppp-negotiate
[LAC-Virtual-PPP1] ppp pap local-user vpdnuser password simple Hello
[LAC-Virtual-PPP1] quit
# Configure a static route so that packets destined for the corporate network will be forwarded
through the L2TP tunnel.
[LAC] ip route-static 10.1.0.0 16 virtual-ppp 1
# Trigger the LAC to establish an L2TP tunnel with the LNS.
[LAC] interface virtual-ppp 1
[LAC-Virtual-PPP1] l2tp-auto-client l2tp-group 1
3. On the remote host, configure the LAC as the gateway.
Verifying the configuration
# On the LNS, use the display l2tp session command to display the established L2TP session.
[LNS] display l2tp session

# On the LNS, verify that you can ping 10.2.0.1, a private network address on the LAC side. This
indicates that hosts on 10.2.0.0/16 and those on 10.1.0.0/16 can communicate with each other
through the L2TP tunnel.
