Then it seems the VLs don't go up because you don't have an interface
declared under area 0 on R2 or R5. I just tried it in the lab, the VLs
won't raise unless you have a valid 'network X.X.X.X X.X.X.X area 0'
statement on one of the routers. It makes sense because VLs are used to
link to the backbone area, so this area should be active.
