Internal Network Number
This is a logical network number that identifies an individual Novell server. It is needed to specify a
route to the services (i.e., file services, print services) that Novell offers. It must be a unique number.
External Network (a.k.a. IPX Network Number)
This number refers to a physical LAN/wire network segment to which servers, routers, and PCs are
connected (Ethernet cable-to-router segment). It must be a unique number.
WAN Network Number
Important: This number is part of the routing information. It is only used to identify the WAN segment
between the two routers.
Note: Only the two routers need to have the WAN Network Number configured.
Service Advertisement Protocol (SAP)
SAP entries should reflect primary logon servers for the clients on the local LAN. Only the servers on the
remote side of the link have to be entered. Local servers do not need to be entered.
Frame Type
With local servers on your LAN, make sure to select the proper frame type for the IPX network number.
To determine this, consult with your network administrator. When you have only NetWare clients on
your LAN, keep the default (802.2) selected as most clients can support any type.
The frame type choices are:
802.2Default recommended by Novell
802.3Other most common type
DIXFor DEC, Intel, Xerox; this setting is also referred to as ÒEthernet IIÓ, and it is rapidly
becoming obsolete.

VPI and VCI Numbers (with RFC 1483)
The VPI and VCI numbers apply to ATM routers only. 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 (with RFC 1490)
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.
