USER’S GUIDE

See illustration, Example 1. Because SITE1 is the only CyberSWITCH that is connected to the logical network, it is reasonable for SITE1 to advertise the IP RIP information on Network 3 as subnetwork routes, meaning that SITE1 will always advertise the remote IP devices’ IP RIP information.

Network 1 (1.0.0.0)

i/f 1 1.0.0.1

R 1

i/f 2 2.0.0.1

Network 2 (2.0.0.0)

i/f 1 2.0.0.2

CSX1200 "SITE1"

i/f 2 3.0.0.2

3.0.0.11 ISDN 3.0.0.12

3.0.0.13

Network 3

(3.0.0.0)

WAN RIP Interfaces: Example 1

Suppose there is a second CyberSWITCH that belongs to the logical Network 3, as shown in Example 2. It is better for SITE1 and SITE2 to advertise the IP RIP information for each of the remote devices on the logical network on each IP Host device as it connects to the system.
