IP Map/RIP Method
Write security: 3, Read security: 5
The way the RIP protocol sends out its advertisements is specified here:
None - All routes in the router table are advertised out this
virtual circuit with no modification of the metrics.
Split Horizon (def) - Only routes not learned from this particular
virtual circuit are advertised.
Poison Reverse - All routes are advertised, but the routes learned
from this port are “poisoned” with an infinite metric.
IP Map/RIP Direction
Write security: 3, Read security: 5
This parameter allows the direction at which RIP advertisements are sent and
listened to be specified.
Tx and Rx (def) - RIP advertisements are periodically transmitted and
are listened to on this virtual circuit.
Tx Only - RIP advertisements are periodically transmitted but are not
listened to on this virtual circuit.
Rx Only - RIP is not transmitted on this virtual circuit but they are
listened to.
IP Map/NAT
The Express L128/L128T can perform Network Address Translation over a
PVC. Setting this option to On will cause the Express L128/L128T to translate
between the Ethernet addresses and the configured Link IP Address. Only
one PVC may be used for translation at one time. If more than one IP Map is
configured for NAT, the first PVC which is activated becomes the NAT port.
DLCI Mapping/IPX Map
This menu represents the IPX protocol mapping that is to take place for this
DLCI.
IPX Map/Active
Write security: 3, Read security: 5
When this is set to Yes (def), the Express L128/L128T will attempt to transport
IPX packets for this DLCI. A setting of No means that no IPX traffic or route
will be exchanged.
