         Topology as:

          R3
           |
          R4
           |
          R5-----R2---R1
           | |
          R6 (AS 20)

OSPF run among them.

Now R1, R2, R3 in AS 1, R2 as Route Reflector. Without
BGP on R4. R5 in AS 2.

Reqiurement:

R3 and R6 propagate their lo 1 into BGP,
They are 199.100.1.0 and 199.101.1.0

1. routes from AS 20 needed to be reachable from all
BGP routers.

2. routes for lo 1 of R3 and R6 should be reachable
from any routers runing BGP.
 
3. propagate only one route into AS 2 for lo 1 of R3
and R6.

4. routes from AS 20 should be appeared as BGP routes
on all BGP routers.

How to satisfy all these at the same time?
