Assigning Internet Addresses 6-21
Assigning Internet
Addresses to a Router
If the bridge/router is used to route IP traffic, you must configure the ports on which
IP packets are routed by assigning Internet addresses to them. You can assign
Internet addresses to individual ports using:
SETDefault !<port> -IP NETaddr = <IP address>
For more information, refer to the Reference for NETBuilder Family Software.
CAUTION: Do not assign an Internet address to port 0, or the IP routing function will
be disabled.
The next example illustrates how to assign Internet addresses to a bridge/router.
Example In Figure 6-4, Networks A and B are two different IP networks, and the bridge/router
is used for routing IP packets and for bridging OSI packets. To assign an IP address to
port 1, enter a command similar to the following:
SETDefault !1 -IP NETaddr = 192.1.5.1
To assign an address to port 2, enter a command similar to the following:
SETDefault !2 -IP NETaddr = 192.1.3.1

For additional information on Internet addresses and subnet masks, refer to Using
NETBuilder Family Software. After assigning an Internet address or addresses to the
bridge/router, proceed to Chapter 1 in Using NETBuilder Family Software.
Obtaining an
Internet Address
If you want to connect your TCP/IP network to the Internet, you must obtain a
unique address from the central authority, the InterNIC. This central authority
provides the following services:
■ Registration Services
Assists in registering networks and domains, and assigns network numbers and
other entities to the Internet community.
■ Directory and Database Services
Maintains lists of FTP sites, various types of servers available on the Internet,
white and yellow page directories, library catalogs, and data archives. For more
information, phone (908) 668-6587 or use network mail
(admin@ds.internic.net).
■ Information Services
Offers information about how to get connected to the Internet, pointers to
network tools and resources, and seminars on various topics held in locations
around the country. For more information, phone (800) 444-4345 or use
network mail (info@internic.net).
Network A
Assign an IP address
to Port 1 so that the
bridge/router can boot
from the TFTP server
Assign an IP address
to Port 2 so that the
host can access the
bridge/router via Telnet
