Transiting Non-BGP Speaking Devices

Hi Guys, I know this is a very newbie question, but it keeps spinning in my
head.

Ok this is the dilemma

R1 --- R3 ---- R2

R1-R2-R3 runs any IGP.

R1 and R2 are running BGP in AS 12 and they peer via each other Loopback
Address (/32 BTW).

So, I need to solve the Non-BGP Transitive Device Problem, I know that I can
use tunnels or maybe redistribute BGP routes at R2 and R1.

But the question is more difficult (for me at least); say that I add another
2 BGP Devices connected to R3

          R5
          .
          .
R1 ------ R3 ------ R2
          .
          .
          R4

I need to create a full mesh BGP Session between R1; R2; R5; R4 using their
loopbacks Address (/32 BTW).

So creating tunnels here is out of the game, because you can not add extra
Ip addressing.

Now redistributing the BGP Routes to the current IGP, would NOT help me if I
need to create some AS Policies. - Like Local Preference.

Maybe MPLS would solve the problem (do not know how to configure, and I
think that would be out of the scope of the CCIE Lab for now)

Any recommendations for this particular problem?

Thanks
Victor.-
