Refer to "Configuring Multilink Frame Relay" on page 258
about MFR interface parameters.
A virtual template (VT) is a template used for configuring a virtual access (VA)
interface. VTs are mainly used in VPN and MP implementations.
After a VPN session is established, a VA interface is necessary for data exchange
with the peer end. In this case, the system will select a VT based on the user
configurations, and then create a VA interface dynamically. Refer to
VPN Instances" on page 1481
When multiple PPP links are bundled into an MP, a VA interface is also necessary
for data exchange with the peer end. In this case, the system will also select a VT
so as to create a VA interface dynamically. Refer to
on page 363 for more information about MP.
In VPN and MP implementations, creation and removal of VA interfaces are
automatic and transparent to users. You just need to configure VPN or MP on the
corresponding physical interface, create and configure a VT, and then associate
this VT with the corresponding physical interface.
