3. Define IPX circuits
On the Head Office router define two IPX circuits, one for the Ethernet
interface and one for the wide area link. To configure the wide area link as
a demand link and enable RIP and SAP change broadcasts, enter the
commands:
ADD IPX CIRC=1 INT=ETH0 NETW=401 ENCAP=802.3
ADD IPX CIRC=2 INT=PPP0 NETW=129 DEMAND=ON
SET IPX CIRC=2 RIPCHANGE=YES SAPCHANGE=YES
Repeat this procedure on the Remote Office router, defining one IPX circuit
for the Ethernet interface and one for the wide area link. To configure the
wide area link as a demand link and enable RIP and SAP change
broadcasts, enter the commands:
ADD IPX CIRC=1 INT=ETH0 NETW=12 ENCAP=802.3
ADD IPX CIRC=2 INT=PPP0 NETW=129 DEMAND=ON
SET IPX CIRC=2 RIPCHANGE=YES SAPCHANGE=YES
The routers are now configured for IPX dial-on-demand and can exchange
routes and service information.
4. Save configuration
Save the new dynamic configuration as a script, by entering the command:
CREATE CONFIG=IPXDOD.SCP
The link is activated (the ISDN call is connected) whenever data is waiting to
transmit over the wide area link, and deactivated when no data is transmitted
over the link for a period of time. The link is also activated whenever there is a
change of route or service information, to allow the exchange of RIP and SAP
updates. To improve performance, you can configure RIP and SAP filters on
the Head Office router to limit the number and size of broadcasts which
activate the ISDN call.
To configure RIP and SAP filters, follow these steps on the Head Office
router only:
1. Create RIP filter
To create a RIP filter that only allows information about route changes to
the file server's internal network (network number 7500) to be included in
RIP broadcasts, enter the command:
ADD IPX RIP=0 NET=7500 ACTION=INCLUDE
2. Create SAP filter
To create a SAP filter that only allows information about the file services
provided by the file server (named ACCOUNTS) to be included in SAP
broadcasts, enter the command:
ADD IPX SAP=0 SERVICE=ACCOUNTS TYPE=FILE ACTION=INCLUDE
3. Associate RIP and SAP filters with IPX circuit
To associate the RIP and SAP filters with the IPX circuit over the PPP link,
enter the command:
SET IPX CIRC=2 RIPCHANGE=YES SAPCHANGE=YES OUTRIP=0
OUTSAP=0
