In-Depth Information
Verify that AS 200 still receives all three prefixes from AS 100. Example 8-22 shows the
BGP RIB on R8. This shows the same BGP RIB as before the migration.

Final BGP Configurations
This section summarizes the relevant BGP configurations after the migration of a few
selected routers. Two configurations are shown: one for an RR, and one for a client.
Example 8-23 shows the final BGP configurations on R1.
