regarded R2 as an alternate path to Net 1.

The second is called “poison reverse,” which stipulates that routes are advertised as unreachable on the interface on which the route is learned. Had poison reverse been used in the preceding example, R2 would have advertised Net 1 as unreachable in its RIP updates to R1. Again R1 would never have regarded R2 as an alternate path to Net 1.

Digi One/PortServer TS 2/4’ s participation in the exchange of RIP updates can be configured on the set forwarding command. This command allows you to configure Digi One/PortServer TS 2/4

To neither receive nor propagate RIP updates (state=off), which means it must be configured for static routes (set route command) if it is to do any routing at all.
