IPX Routing Network Protocol

System Names and Authentication Passwords

For the Target Router

You define the system name and authentication password for the target router. A system name and

authentication password are required because they are used by a remote router to authenticate the target

router.

For the Remote Site(s)

The Network Service Provider defined the system names and authentication passwords for the remote

routers. You must have this information because it is used by the target router to authenticate the remote

router. The name and password are used in both PAP and CHAP authentication. To see how this

information is used, refer to the diagram under PAP/CHAP Security Authentication, on page 22 .

Note: If the NSP does not support the authentication of the NSP system by the target router, use the

command remote disauthen <remoteName> to disable the authentication process.

Note: A sample configuration containing names and passwords is provided in the section Sample

Configuration 1: PPP with IP and IPX, on page 61

VPI and VCI Numbers

Your router may have been preconfigured with VPI/VCI numbers. If not, you will have to obtain these

numbers from your Network Service Provider and then configure them.

If you are connecting to multiple remote sites, you will need to obtain additional VPI and VCI numbers

from your Network Service Provider and/or Network Access Provider. These numbers identify the

remote destination and must, therefore, be unique for each remote.

DLCI (for Frame-Relay Routers)

The DLCI number applies to Frame-Relay routers only. Your Network Service Provider or your

Network Access Provider will provide you with a Data Link Connection Identifier (DLCI). The DLCI is

an address identifying your connection.

IPX Routing Entries

These numbers are defined by the Network Administrator. You will need to obtain the following

information (most likely from your network administrator) for IPX Routing.

Note: IPX routes define a path to a specific destination. They are primarily needed by the routers to

allow the servers and clients to exchange packets. A path to a file server will be based on the Internal

Network Number of the server. A path to a client will be based on the External Network Number

(Ethernet) of the client.
