The flow of routing information used in selection of a route and network
interface (circuit group) involves the routing protocols (RIP, ARP, OSPF,
etc.) primarily. This flow is different for each bridging and routing service.
For some services, the path can involve numerous choices of routing
protocol and can involve other features as well, such as the import and
export route filters for the IP routing service. The most complex flow is for
IP, as shown in figure 7. Figure 8 shows the flow for IPX.
These diagrams of the flow of routing information complement the diagram
of the flow of the actual data packets (which are most of the packets
transmitted) in figure 6.
