Example 8-61 shows the BGP RIB on R1. Note that the prefix 192.168.201.0/24 is learned
from member AS 65001.

Example 8-62 shows the current BGP RIB on R8. All prefixes from AS 100 are received
correctly.

At this stage, there is no BGP redundancy in part of the network. The current topology is
shown in Figure 8-11.
