Example 8-18 shows the BGP RIB on R7 after the session cleanup. For each prefix that is
not locally originated, two paths are now available.

Example 8-19 shows the detailed path information for the prefix 172.16.0.0/16 on R7. Both
paths are reflected, one from each RR.

Step 6: Repeat Steps 1 Through 5 for the Other POP
Repeat Steps 1 through 5 for the remaining POPs. In this case study, there is one remaining
POP left to migrate.
