Step 5: Move R6 from Member AS 100 to Member AS 65001 and Put R4 Back in the
Forwarding Paths
Move R6 into member AS 65001, which is service-affecting for the prefix originated
locally on the router. Example 8-30 shows the new BGP configurations on R6. Note that
R6 is not peered with any router in the other POP.
