IP Map/RIP
IP Map/NAT
The TA 850 can perform Network Address Translation over a PVC. Setting this option to On will cause
the TA 850 to translate between the Ethernet addresses and the configured L
OCAL
IP A
DDRESS
.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
When this is set to Yes, the TA 850 will attempt to transport IPX packets for this DLCI. A setting of
No (def) means that no IPX traffic or route will be exchanged.
IPX Map/IARP
When this is set to Yes, the TA 850 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 (def) means that the IPX network is to be assigned to the link statically using the IPX
Map/Link Network parameter. The TA 850 will always respond to Inverse ARP requests.
IPX Map/Link Network
This is the IPX network of the link or of the other device’s LAN. When this DLCI becomes active, the
TA 850 will add a route to this network in the IPX routing table. This address is also used by the TA 850
RIP /V
ERSION
The RIP protocol can be specified per DLCI.
The possible selections are Off (default)
(meaning no RIP packets are listened to or
sent), V1 (def) (which is RIP version 1) or V2
(which is RIP version 2).
RIP/M
ETHOD
This specifies the way the RIP protocol sends
out its advertisements.
N
ONE
(
DEF
)
All routes in the router table are advertised out
this virtual circuit with no modification of the
metrics.
S
PLIT
H
ORIZON
(
DEF
)
Only routes not learned from this particular
virtual circuit are advertised.
P
OISON
R
EVERSE
All routes are advertised, but the routes
learned from this port are “poisoned” with an
infinite metric.
RIP/DIRECTION
This parameter specifies the direction at which
RIP advertisements are sent and listened.
T
XAND
R
X
(
DEF
)
RIP advertisements are periodically transmit-
ted and are listened to on this virtual circuit.
T
X
O
NLY
RIP advertisements are periodically transmit-
ted but are not listened to on this virtual circuit.
R
X
O
NLY
RIP is not transmitted on this virtual circuit but
they are listened to.
