IP, IPX, and AppleTalk Dial-Up Environments 5-9

Configuring Point-to-Point Protocol (PPP) Access

Step 3 Set the IPX network number and encapsulation to match your existing network. The

following example shows network 123ABCD and an encapsulation type of SAP:

2511(config-if)# ipx network 123ABCD encapsulation SAP

Step 4 If the client connecting to the network is not performing routing, you do not have to

enable a routing protocol and can skip to the next step. If the client connecting to the

network is performing routing, conﬁgure a routing protocol. RIP routing is enabled by

default. To specify a different routing protocol, such as Enhanced IGRP or NLSP, enter

the ipx router command, followed by the name of the routing protocol.

The ﬁrst example shows how to enable Enhanced IGRP routing with an autonomous

system number of 1205. Enhanced IGRP is usually used in large networks.

2511(config)# ipx router eigrp 1205

The next example shows how to enable NLSP routing with an NLSP process tag of 210.

An NLSP tag is optional if there is only one NLSP process. The process of conﬁguring

NLSP is somewhat complex and you must add NLSP servers to the network.

2511(config)# ipx router nlsp 210

Creating a Loopback Interface for Novell IPX Network Numbers

If you allow remote clients to dial in to IPX network resources, you should create a loopback

interface, which is a “virtual” interface existing only in the router. Assign a Novell IPX network

number to this loopback interface, then assign this network number to each asynchronous interface.

The alternative is to assign a unique Novell IPX network number to each asynchronous interface,

which could consume hundreds of Novell IPX network numbers. This section assumes that

nonrouting clients are dialing in to access IPX network resources.

Note Follow these steps only if you IPX clients are nonrouting clients. If they are routing clients,

you must assign a unique IPX network number to each asynchronous interface and you cannot use

group asynchronous interfaces, because there is no way to assign a unique IPX network number to

each interface in a group.

Step 1 Create a loopback interface:

2511(config-if)# interface Loopback0

Step 2 Do not require an IP address on the Loopback interface 0:

2511(config-if)# no ip address

Step 3 Assign a Novell IPX network number (in this case, 1F) to the loopback interface:

2511(config-if)# ipx network 1F
