The SFVRA-CFG Network
Two sites can communicate by one or more connections that use circuits. A connection between two
systems uses circuits at each end, one attached to each system. The graphic below illustrates the
variety of circuits that can be used in an SFVRA-CFG network.
In addition to defining the physical topology of the network, the administrator also defines the
virtual topology for each major network protocol. There is a separate protocol view for IP, IPX, and
AppleTalk.
The SFVRA-CFG captures the definition of each subnet and segment, and how each system
interfaces to it. This helps to generate all systems’ configurations as well as any routing tables that
are needed.
