Step 6: Move R5 from Member AS 65001 to Member AS 100
Move R5 from member AS 65001 to member AS 100, as in Step 2. Create a new peer group
called Internal for future peerings with all other RRs. Currently, only R4 is a member of the
peer group Internal. Create a peer group called Clients that includes R6 and R7. Example 8-96
shows the new BGP configurations on R5.
