Re: Frame Relay Interface Configuration problem

I always have a problem with interpreting this type of questions.

If the requirement states that all configuration must be on the physical
interface, what is the difference between using a virtual template and a
subinterface?
Both a virtual template and subinterface are logical interface attached to
the physical interface.

The requirement states: "All configurations should be done on the physical
interface"

In the case of a PPP virtual template, all configuration is not on the
physical interface...Some is on a virtual template
The IP address for instance is NOT on the physical interface.

Thanks in advance,

Chris
