This example depicts use of the maximum number of LAN Connections. At the
regional site is a Vanguard that needs to connect with up to 254 branch sites over
Frame Relay. Frame Relay supports a 254 DLCI maximum per node and permanent
SVCs only. These LCONs can be connected in any combination of router interfaces
and bridge links as long as the total capacity is not exceeded. Supported
encapsulation types over Frame Relay are Codex Proprietary and RFC1294/1490.
Figure 2-5 shows this example.
