5.5.3 Partially Meshed Frame Relay Network (Different IP Network)
The Frame Relay router should be able to support different IP networks inside Frame Relay,
so that partially meshed Frame Relay networks can be “split” into different full-meshed Frame
Relay “subinterfaces.” This IP network comprises of routers A, B and C is called
point-to-multipoint (or a group mode WAN interface). A topology between routers B and D,
as well as between routers E and D is called point-to-point (or a direct mode WAN interface).
Figure 5-7 shows a partially meshed frame relay network with full connectivity using different
IP network capabilities with three networks and five locations.
