IPX Map/IARP

Write security: 3, Read security: 5

When this is set to

Yes

(def), the Express L768 will send Inverse ARP

packets to determine the IPX network on the other end of the virtual
circuit. If the IARP is responded to, a route is placed in the IPX route
table. A setting of

No

means that the IPX network is to be assigned to

the link statically using the IPX Map/Link Network parameter. The
Express L768 will always respond to Inverse ARP requests.

IPX Map/Link Network

Write security: 3, Read security: 5

This is the IPX network of the link or of the other device’s LAN. When
this DLCI becomes active, the Express L768 will add a route to this net-
work in the IPX routing table. This address is also used by the Express
L768 to respond to Inverse ARP requests. If this IPX address is left as
0, the link is treated as unnumbered and the Express L768 responds to
the Inverse ARP with its Ethernet IPX address.

DLCI Mapping/Bridge Map

This menu is used to permit bridging of packets over this DLCI. Each
DLCI or virtual circuit must be assigned a bridge group. The bridge
group treats all virtual circuits as one circuit. Bridge packets destined
to be transmitted out a particular bridge group are copied and trans-
mitted individually out each DLCI in the bridge group. However, in-
coming bridge packets received from one DLCI are not retransmitted
out the other DLCIs in the same bridge group. Any device in the
bridge group must transmit to each DLCI. This requires a fully
meshed circuit, meaning each device has a virtual circuit to each other.

Bridge Map/Active

Write security: 3, Read security: 5

When this is set to

Yes

(def), the Express L768 will bridge packets to

and from this DLCI. Bridge packets are any packets that are not IP or
IPX packets except when the router is turned off, in which case that
particular router’s protocol packets are bridged. A setting of

No

means that no bridging will occur.
