116 CHAPTER 8: CONFIGURATION OF L2TP
These configurations are compulsory on LNS side.
Perform the following configuration in system view.
By default, L2TP is disabled.
Enabling/Disabling the
L2TP Multi-Domain
Function
A security gateway can function as LNS for multiple enterprises only when the
L2TP multi-domain function is enabled. The L2TP multi-domain function can be
implemented to diversify VPN networking modes.
In L2TP multi-domain applications, these configurations are compulsory at LNS
side.
Perform the following configuration in system view.
By default, the L2TP multi-domain function is disabled.
Creating L2TP Group L2TP group needs to be created in order to fulfill related parameter configurations
of L2TP. It allows you not only to configure L2TP functions on the security gateway
as needed but also to implement one-to-one and one-to-many networking
applications between LAC and LNS easily. L2TP groups are numbered separately
on LAC and LNS, so LAC and LNS only need to keep consistent in the
configurations of the involved L2TP groups such as remote name of Tunnel, start
L2TP and LNS address.
These configurations are compulsory on LNS side.
Perform the following configuration in system view.
After L2TP group is created, other configurations related to the L2TP group can be
performed in L2TP group view, for example, local name and remote name of
Tunnel.
By default, no L2TP group is created.
