Step 4: Move R6 from Member AS 65001 to Member AS 100 and Put R4 Back in the
Forwarding Paths
Move R6 from member AS 65001 to member AS 100. On R6, create a peer group called
Internal for sessions with its future RRs, R4 and R5. Example 8-90 shows the new BGP
configurations on R6. Note that R6 peers only with the two core routers in the same POP.
