3Com NETBuilder SI, SuperStack II manual Traffic from one site to another over the same parent port

Configuring Frame Relay 95

Scenario 2: Partially A partially meshed topology consists of bridge/routers that are connected Meshed Topology directly to some destinations but not others. Use virtual ports to pass

traffic from one site to another over the same parent port.

Instead of using virtual ports (if you run out of virtual ports, for example), you can use the next-hop split horizon feature in the routing protocol. See Using Enterprise OS Software for more information.

In this scenario, site B is not connected to site C, and site A is not connected to site D. Create virtual ports on site A so traffic from site B can pass through site A to get to site C. Create virtual ports on site C so traffic from site D can pass through site C to get to site A. For redundancy, you can create virtual ports on site B and site D as well.
