Step 2 Try to establish IP connectivity (using the ping or tracert commands).
a. “Pinging” from the L2TP client or LNS to the opposite tunnel endpoint should
succeed (this tests the tunnel path).
b. “Pinging” from a tunnel endpoint IP address to an IP address within the tunnel
will probably fail due to the existence of the IP firewall.
Task Complete
Configuration Commands
L2TP configuration commands are used to configure:
• Tunnels
• The PPP session
Commands to configure tunnels
For additional information, see Chapter 9, L2TP Commands in the Command Line
Interface Guide.
Add an L2TP tunnel entry by name:
-> l2tp add <tunnelname>
The remote tunnel host name:
-> l2tp set remotename <name> <tunnelname>
The local tunnel host name:
-> l2tp set ourtunnelname <name> <tunnelname>
CHAP secret:
-> l2tp set chapsecret <secret> <tunnelname>
Tunnel authentication:
-> l2tp set authen on | off <tunnelname>
Type of L2TP support for tunnel: Configure the entry to act as a L2TP client, an L2TP
network server (LNS), or as both a LAC and an LNS, or the entry can be disabled.
-> l2tp set type all | lns | l2tpclient | disabled <tunnelname>
Remote tunnel IP address:
-> l2tp set address <ipaddr> <tunnelname>
