Table 2-23 Set parameters for call receiving
Set remote name of tunnel (L2TP group
not being 1).
Set remote name of tunnel (L2TP group
being 1).
Remove remote name of tunnel
When the group number of L2TP is 1 (the default L2TP group number), you do not need
to specify remote-name. If remote-name is specified in L2TP group view 1, L2TP group
1 will not be regarded as the default L2TP group.
Note:
Only L2TP group 1 can be set as default group.
Any computer can initiates a tunnel setup request when L2TP group 1 (the default
group) is set.
The start command and the allow command are mutually exclusive to each other.
After one is configured, another one goes invalid automatically.
2.3.6 Setting Tunnel Authentication and Password
As needed, a user can decide whether to start tunnel authentication before creating
tunnel connection. Tunnel authentication request can be sent by either LAC side or
LNS side. If one end of a tunnel starts tunnel authentication, the other end must also
start tunnel authentication in order to set up the tunnel connection. In addition, both
ends must use the same password, which cannot be void. Otherwise, the local end will
disconnect the tunnel automatically. If tunnel authentication is disabled on both ends,
the consistency of password will be insignificant.
These configurations are optional on LNS side.
Perform the following configuration in L2TP group view.
