dynamically create a virtual interface based on the configuration parameters of the
template.
Similarly, after multiple PPP links are bound as MP, a virtual interface also needs to
be created to exchange data with the opposite end. At this time, select an
interface template to dynamically create a virtual interface.
Configure In VPN and MP application environments, the system automatically creates and
Virtual-Template deletes virtual interface, which is completely transparent to the user. The user only
needs to configure VPN or MP at corresponding physical interface, create and
configure virtual-template and then build up relation between the virtual-template
and relevant physical interface.
Virtual-template configuration includes:
1 Create and delete virtual-template
Please use the following commands in all views.
Table 192 Create or delete virtual-template
Here, number stands for template number of virtual-template ranging 1 to 25, i.e.
the user can create up to 25 virtual-templates.
In executing
virtual-template has been created, then directly enter the view of this
virtual-template. Otherwise, first create the virtual-template with specified
template number.
In deleting the virtual-template, make sure that all of its derived virtual interfaces
have been removed and this virtual-template is not in use any more.
2 Set work parameters of virtual-template
Compared with normal physical interface, the virtual-template has the following
features: the link layer protocol only supports PPP, and the network protocol
supports IP and IPX. Therefore, the following working parameters can be set:
Settings of these parameters on virtual-template are the same as those on normal
interface. Please see related chapters of PPP configuration in Operation Manual –
Link Layer Protocol, IP address configuration in Operation Manual – Network
Protocol and RADIUS configuration in Operation Manual – Security for
configuration details.
