Overview
CBF connections forward frames along connections configured between pairs of interfaces. Frames received on a connection's ingress interface are forwarded directly to that connection's egress interface. The packet is transmitted from ingress to egress forwarding interfaces as the raw layer 2 payload received from the layer 2 interface. Both the ingress and egress interfaces are SMDS-encapsulated or bridged-IP encapsulated and have CBF interfaces associated with them. Once the connection between the ingress and egress interfaces is made, traffic begins to flow.
