Vanguard Routing Model
T0100-01, Revision B
The following examples illustrate LAN traffic encapsulation by
• Codex Proprietary Encapsulation
• Frame Relay - RFC 1294 and RFC 1490
Figure 2-4 depicts LAN traffic encapsulated by Codex Proprietary Encapsulation for
transport over an X.25 network. At the regional site a Vanguard connects with up to
254 branch sites over X.25. The encapsulation type should be Codex Proprietary due
to the RFC limitation of supporting only a single call. The LCONs can be connected
in any combination of Router Interfaces (On Demand or Permanent SVCs) and
Bridge Links (Permanent SVCs only) as long as the total capacity is not exceeded.
