Dual LAN Ethernet
Routing
In IP/IPX or AppleTalk routing environments, do not connect both Ethernet LAN
ports to the same Ethernet segment with identical routing decision values. This is not
supported.
How to Configure
Dual Ethernet LAN
Follow these steps to configure a node for Multiple Ethernet LAN.
Step Action Result/Description
1 Make a local CTP connection to a
PathBuilder S24x, 26x, and 27x
switch. The CTP is physically connected to
the device you are configuring.
2 Select Configure -> Port from the
CTP Main menu. The Port record appears.
3 Configure the Port record as you
normally do for an Ethernet LAN
connection. Two new parameters, Bridge Link
Number and Router Interface,
appear in the record.
4 At the Bridge Link Number:
parameter, type in a number 1-4 to
identify the bridge link, and press
Return.
Note
The default value for this
parameter is 1.
This matches this port configuration
to a specific bridge link number
within the bridging configuration. If
the bridge link you select is already
used, a warning message appears,
but your input is retained in the
CMEM.
5 At the Router Interface Number:
parameter, type in a number 1-4 to
identity the router interface.
Note
The default value for this
parameter is 1.
This matches this port configuration
to a router link number within the
router configuration. If the router
interface number you select is
already used, a warning message
appears, but your input is retained
in the CMEM.
6 Type; and press Return to save the
record. This saves the record.

following step. By default, the
bridge link is not activated until you
activate it.
