[c-nsp] MPLS or ?

[Tom Storey]

If you are only using one router to terminate all circuits, and there  
are no other routers involved, MPLS doesnt come into the picture.

All you need to do is define two VRFs on your router, place the  
respective circuits into each of those VRFs, add some static routes as  
required, and youre done.

If there is going to be more than one router involved, perhaps at  
different locations throughout the network, you then could/would use  
MPLS.

I say could/would because you can link VRFs from different routers  
together using tunnels and static routes or routing protocols to take  
care of the routing.

MPLS only comes into the picture when you are switching traffic around  
the network using labels. A single router can just be a collection of  
VRFs without MPLS being involved.
