Assigning Internet Addresses 6-21

Assigning Internet If the bridge/router is used to route IP traffic, you must configure the ports on which Addresses to a Router 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
