Experiment Description:
1. The need to configure static routes on three routers in order to achieve interoperability between the various segments 2. To achieve full network interoperability, two questions must be clarified as follows router packet is forwarded or dropped, depending on whether the route can entry router table to find the data packets corresponding to the target address can be automatically generated routing entries all directly connected network, for the network segments that are not directly need to specify a static routing 3. Accordingly, the whole network in order to achieve interoperability, All entries must specify the routing of non-directly connected network segments for each router
