STEP THREE
Figure 9.5 shows an example of a route that could be filtered out. The preferred route from 5 to 1 is through 4, with
6 serving as a reliable backup. Any route received from neighbor 2 which includes 5 will probably be a duplicate
of the equivalent route received from 4. In order to reduce the size of the routing table, all routes received from 2
than contain 5 can be filtered out of incoming update messages.
