dnis dialed-number: Number dialed by the user triggering the connection request,

Description
Using the start l2tp command, you can configure the triggering conditions for
originating a call when the local end servers as L2TP LAC end. Using the undo start
l2tp command, you can cancel the specified triggering conditions .
This command can only be used on LAC, which is .
This command is used to specify the IP address of LNS. It supports multiple methods
of connection triggering request.
A tunnel connecting request can be originated based on the domain name of the
user. For example, if the domain name of a company to which a user belongs is
huawei.com, then the user who contains this domain name can be specified as a
VPN user.
You can determine whether or not the user is a VPN user according to the dialed
numbers. For example,if the number 8810188 is specified as the special service
number, any accessing users dialing this number will be VPN users.
You can also specify a user to be a VPN user directly by the user's full name.
If the user is a VPN user, the local end (LAC) will send a L2TP tunnel connecting
request to one of the LNSs according to the LNS sequence configured. Once LAC
receives the response from LNS, this LNS will become the peer-end of the tunnel.
Otherwise, LAC will send the tunnel connecting request to the next LNS.
There may be conflicts between these methods of identifying VPN users. For example,
the LNS address specified based on full user names is 1.1.1.1, while that based on
the domain names is 1.1.1.2. In this case, it is necessary to specify the order to
search for VPN users. The searching sequence is as follow: First, check if there is a
L2TP group specified according to the full user names. If not, search according to the
order of the domain names. The searching order which bases on domain name is set
by the l2tp match-order command.
For related commands, see l2tp domain, l2tp match-order.
Example
# Identify VPN users in L2TP group 1 according to the domain name 3com.com. The
IP address of the corresponding LNS at its headquarters is 202.38.168.1.
[3Com-l2tp1] start l2tp ip 202.38.168.1 domain 3com.com
