Now put R4 back in the forwarding paths. Verify that prefix 172.16.0.0/16 is available on
R4 and R6 and that prefix 192.168.201.0/24 is available on all the routers in member AS 100
and on R8.
Example 8-60 shows the BGP summary table on R4. As expected, the sessions with R5 and
R7 are still down. Ignore the messages about the wrong AS.
