You can use the dual NIC (or multiple network interface) capabilities of each client or server, enabling you to specify a complete and unique network connection from a client to a server.
Consider the following diagram:
The above example shows two levels of redundancy:
Each of the system components in the cluster are connected to a second network (LAN 2). This is achieved by using the dual end points of each server. This provides connection to two separate LANs to provide for LAN redundancy as follows:
