IBM 3172 Nways Interconnect Controller connections between APPN nodes

You can use an IBM® 3172 Nways Interconnect Controller connection to connect a composite network node, end node, or network node with any other type of APPN node.

Note: VTAM® uses single-route broadcasts (rather than all-routes broadcasts) when attempting to connect to nodes on token-ring networks attached through the IBM 3172 Nways Interconnect Controller. When a node can be reached only through bridges, there must be a route from the IBM 3172 Nways Interconnect Controller to the node, and that route must traverse bridges that are configured to route single-route broadcasts. See the Token-Ring Network Architecture Reference for more information about all-routes and single-route broadcasts.

Figure 1 shows how to connect two network nodes using IBM Nways Interconnect Controller.
