Scenario: RouteD configuration

You can use this scenario, which shows how RouteD configuration entries work in a sample network, as an example for your own RouteD configuration.

The following figure shows how the RouteD configuration entries work in a sample network. The routers know every route within every network, including networks X, Y, Z, A, and W.

Figure 1. RouteD configuration scenario

• Case 1 – If router AY has an interface of 192.10.2.1, a metric of 1, and a NOFORWARD parameter of 192.50.21.0, then none of the hosts in the networks reach network A.
• Case 2 – If router WZ has an interface of 192.10.3.1, a metric of 1, and a NOFORWARD parameter of 192.10.4.0, then none of the IP packets goes through router WZ to get to network W. IP packets can still reach network W, however, because router WY provides a route to that network.
  Note: If you set the parameter option of any interface to Passive, then no routing takes place across the interface.
