Scenario: Bridged connections to remote token-ring networks

 

This scenario shows how to connect a System i™ model on a frame-relay network to systems on two remote token-ring networks. The 6611 Network Processor and IBM® PS/2® computer-based RouteXpander/2 are used as bridges between the frame-relay network and the remote local area networks (LANs).

The following figure shows the configuration of a System i model for frame-relay communications with devices on two different token-ring networks.

Figure 1. Bridged connections to remote token-ring networks

One token-ring network is connected using a 6611 Network Processor as a bridge. The other is connected using a RouteXpander/2.

The T1 connection into the frame-relay network is configured by using two data link connection identifiers (DLCIs), with each providing a link to one of the bridges. DLCI 32 defines a permanent virtual circuit (PVC) to the RouteXpander, and DLCI 33 defines a PVC to the 6611.

The source route bridging protocol is carried out on both bridges in this configuration. Both Systems Network Architecture (SNA) Advanced Program-to-Program Communication (APPC)/Advanced Peer-to-Peer Networking (APPN) and TCP/IP traffic are possible in these configurations. The TCP/IP configuration for lines ROUTE6611 and ROUTEEX is done similarly to the way all token-ring network lines are configured for TCP/IP on the System i platform.
