General Configuration Using Local ManagementCSX200 Family User’s Guide 131IPX Routing over Frame RelayAn additional step is required when routing IPX over Frame Relay. This step requires that entriesare created in the IPX Host Map. The IPX Host Map is a database of remote IPX hosts that aredefined generally by the WAN Network number and MAC Address, and more specifically by theInterface Number and Data Link Connection Identifier (DLCI). The IPX Host Map helps a routingdecision by determining which circuit a packet should be forwarded to in a point to multi-pointFrame Relay connection.Figure 61 shows how IPX Host Map entries are entered using the circuitmap command. Thecircuitmap command is accessed from the MIB Navigator Screen. Refer to Chapter 8 for moreinformation on the circuitmap command.Figure 61 Circuitmap CommandThe circuitmap command contains the following fields:#Interface — An entry must be created for each remote Router connected via the Frame Relayinterface.Network — The Network is the IPX Network number associated with the Frame Relay network.Node — The Node is the MAC address of the remote router on the other end of the WAN link.Circuit ID — The Circuit ID is the DLCI identifying the virtual circuit connection to the Telco.Enabling the IPX SAP Routing Protocol on a PortIPX Source Advertisement Protocol (SAP) is used by IPX to exchange information about Novellservice providing nodes, such as file servers and print servers that are available. IPX SAP buildsand maintains a database, the Service Advertisement Table, containing the addresses and routes tospecific service providing nodes, and advertises this information over the network.MIBNav-> circuitmap -s IPX 2 00000172 00:00:1d:02:d1:7a 102i itNetwork00000172Node00:00:1d:23:a1:5bCircuit ID102# Interface# 2
