CIMPLICITY Computer Cabling Redundancy supports two network interface cards (NIC) in each computer.
Each card must be configured for a different
IP network and
Different IP Networks for Cabling Redundancy
There are three different classes of IP Networks.
If you configure one card for an A class IP network and the other for a C class, by default they will be connected to different IP networks.
You can configure each card to the same class IP network. However, you have to make sure that they are, in fact, different IP networks.
You have a Class C IP address 220.127.116.11.
192.68.1 specifies the network that is a Class C status.
135 is a host (specific PC) in the network.
You can configure the second card with a Class C IP address by simply changing the number that is unique to the address.
The Class C IP address may now be 18.104.22.168.
192.68.2 specifies a second network that is a Class C status.
243 is a host (specific PC) in the second network.
You now have two distinct IP networks.
Note: You can use any subnet mask for two IP addresses. However, you cannot use a single subnet mask to differentiate the networks. You have to use a different IP network number for each IP address, disregarding the subnet mask.
Different Physical Networks for Cabling Redundancy
Each of two network interface cards must be connected to its own physical network. This is needed to provide for a backup network in the case that one of the networks is lost.
