Step 12: Move R1 from Member AS 100 to Member AS 65000
Move R1 from member AS 100 to member AS 65000, which is service-affecting between
AS 200 and confederation 100 unless redundant connections exist. This removes member
AS 100 from the topology. Example 8-71 shows the new BGP configurations on R1.
