Bridging: NetVanta 3000 Series Routers

5. Frame-Relay Multipoint – Multipoint bridging applications are useful for two remote offices that
have small traffic requirements and need to access local office resources (desiring minimal
changes to the local and main office servers). If all resources are using NetBEUI protocol,
bridging is the only option. There are minimal differences when configuring point-to-point and
multipoint applications (including frame relay configuration and assigning all sub-interfaces
(PVCs) to the bridge group). The complete configuration for multipoint bridging is shown
below and is annotated to highlight the differences from the point-to-point application.
