Art,
Keep in mind that BGP rides on top of your existing IGP routing domain, so the addresses you peer from/to will affect the IGP path a particular packet takes to get from source to destination.
The choice of interfaces, again, is up to you if not explicitly stated. It might be more practical to select peering interfaces with consideration to the underlying IGP routes packets will take to construct the peering you set forth.
Also, the CCIE lab is results-oriented. If your solution works, you get the points. Period.
HTH,
Ken

Subject: INE Lab 17 BGP 6.1-6.5, In general
On my first pass thru the peering, I used different interfaces than in
the solution. Of course, I had some adj. problems.
In general, for a lab like this with the general instructions for
setting up peering, how do you determine which interface(s)
to use for peering, especially if you have 2 choices?
I'm asking because to use the solutions for 6.8, I had to use the
solution choice of interfaces. With my original choice of peering
interfaces, I had full BGP connectivity but had to use a different
route-map solution (origin-incomplete) to get that to work.
I guess I am asking about the actual lab & how do you select the "best"
or "correct" peering interface for the task requested. I don't
understand how the peering interfaces were chosen for R1, R2, & R3, in
particular, why pick ethernet over the serial links......
