Figure 2-1. Fully Meshed and Non-fully Meshed Networks

Group Access

In group access mode, upper-layer protocols treat each Frame Relay network

interface as a single access point to the switched network. The upper-layer

protocols use a single network address to send all trafﬁc destined for the switched

network to the Frame Relay network interface. When you conﬁgure each router,

you assign only one network address, for example an IP or IPX address, to the

Frame Relay interface, not to each PVC. Figure 2-2 illustrates group access (the

default).
