Configuration Guide
Set the LAC to function as client (optional)
2.2.1 Enabling L2TP
Only after L2TP is enabled can L2TP functions on the router work normally. If L2TP is
disabled, the router cannot provide related functions even if parameters of L2TP have
been configured.
These configurations are compulsory on LAC side.
Perform the following configuration in system view.
Table 2-1 Enable/disable L2TP
Enable L2TP.
Disable L2TP.
By default, L2TP is disabled.
2.2.2 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 as needed but also to
implement one-to-one and one-to-many networking applications between LAC and
LNS. 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 (e.g. remote
name of tunnel , start L2TP and LNS address, etc.).
These configurations are compulsory on LAC side.
Perform the following configuration in system view.
Table 2-2 Create/delete L2TP group
Create L2TP group.
Delete L2TP group.
After a L2TP group is created, other configurations related to the L2TP group can be
performed in L2TP group view, for example, name of peer end, condition triggering
L2TP tunnel setup request and LNS address.
By default, no L2TP group is created.
