Example 8-77 shows the BGP RIB on R8. Note that all prefixes from AS 100 are received
correctly.

Case Study 4: Confederation to Route Reflection
Migration
This case study presents detailed procedures on how to migrate a confederation-based
network into a route reflection-based architecture. Because this case study is the reverse of
Case Study 3, the final topology in Case Study 3 (refer to Figure 8-3) is used as the starting
topology, and the starting topology in Case Study 3 (refer to Figure 8-2) is used as the final
topology.
Starting Configurations
The starting BGP configurations for all the routers are shown in Examples 8-78 through 8-85.
The starting BGP configurations on R1 are slightly different from the final configurations
in Case Study 3 (refer to Example 8-71). To demonstrate a different way to reset the BGP
