Context config>router>l2tp
Description
This command configures the L2TP session limit for the router. L2TP is connection-oriented. The
L2TP Network Server (LNS) and LAC maintain state for each call that is initiated or answered by an
LAC. An L2TP session is created between the LAC and LNS when an end-to-end PPP connection is
established between a remote system and the LNS. Datagrams related to the PPP connection are sent
over the tunnel between the LAC and LNS. There is a one to one relationship between established
L2TP sessions and their associated calls.
Parameters session-limit — Specifies the number of sessions allowed.
Default no session-limit
Values 1 — 131071

no avp-hiding

Parameters avp-hiding — Specifies the method to be used for the authentication of the tunnels in this L2TP
group.
Default no avp-hiding
Values sensitive — AVP hiding is used only for sensitive information (such as username/
password).
