IPX Routing over Frame Relay
An additional step is required when routing IPX over Frame Relay. This step requires that entries
are created in the IPX Host Map. The IPX Host Map is a database of remote IPX hosts that are
defined generally by the WAN Network number and MAC Address, and more specifically by the
Interface Number and Data Link Connection Identifier (DLCI). The IPX Host Map helps a routing
decision by determining which circuit a packet should be forwarded to in a point to multi-point
Frame Relay connection.
Figure 70 shows how IPX Host Map entries are entered using the circuitmap command. The
circuitmap command is accessed from the MIB Navigator Screen . Refer to Chapter 9 for more
information on the circuitmap command.
Figure 70 Circuitmap Command
The circuitmap command contains the following fields:
#Interface — An entry must be created for each remote Router connected via the Frame Relay
interface.
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.
