Partially Meshed Frame Relay Network (Same IP Network)
In this topology, router E (and all the IP nodes behind it) will not reach routers A, B and C
(therefore, all the nodes behind them). This is because there is no direct path between E and
A. In addition, all routing updates from router A will not be heard on routers D and E, and
therefore routers D and E will have no idea about IP nodes behind router A (as well as B and
C). In the real world, IP is rarely fully meshed. Figure 8-6 shows a partially meshed frame
relay network without full connectivity with all the nodes on the same IP network.
