As part of my design for a college course I have been asked to 'spec' the routers and also decide on what technology the data will be delivered on such as broadband or fibre however I need some guidance as I am very unsure if my understanding is right.
Will I need a leased line for each of the separate interfaces going into the routers from each location? I know that this is theoretical but I am assuming that this would be very costly? As it is for a business and downtime would be very costly I am thinking of leased lines using fibre optic (vdsl2).
How would I connect the router to the WAN? I am assuming that the lease fibre line would have a modem. Would I attach a the router to the modem using a serial cable via a serial wan interface card in the router?
I have been trying to work this out rather than ask but I am going round in circles.
Please note that this is a theoretical design and and not real life. My lack of real life experience is obviously an issue when it comes to spec hardware but I have to start somewhere.

This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
