A tunnel session automatically times out after the data session stops. When instructed to
destroy a session, the L2TP client closes any PPP session associated with that session.
The L2TP client may also send control messages to the LNS indicating that the L2TP
client wishes to end the PPP session.
When the LNS wants to hang up the call, it sends control messages destroying the
session.
Configuration
Preliminary Steps to Configure a Tunnel
The following logical steps should be considered before configuring a tunnel:
Step 1 Decide if the router should act as an L2TP Client or LNS.
Step 2 Decide if one side or both sides of the connection should be allowed to initiate a
tunnel.
Step 3 Create the L2TP Tunnel Entry with these characteristics:
The host name of the L2TP client
The host name of the L2TP network server
A Tunnel CHAP secret (both sides of the connection must use the same
secret)
The IP address of the other party must be provided to the initiating side of the
tunnel
Type of flow control (pacing, sequence numbers, or none)
Create a remote entry for the PPP session. Associate the remote entry with
the Tunnel.
Task Complete
Verification Steps
Step 1 Verify that the IP address of the other end of the tunnel is correctly routed through
the right, local interface/remote and will not appear to be routed through the tunnel.
An attempt to route the tunnel endpoint within itself will fail.
