Ipexpert labs have a habit of phrasing questions like this to determine if
you know your stuff or not.
For add loopbacks as necessary watch out for redistribute connected.
For BGP only R5 and R6 have an ebgp peering to R7 in AS 500. The neighbor
10.10.10.7 local-as 600 no-prepend should satisfy the requirement.
