Requirement description

1. Static routes need to be configured on the three routers to achieve interworking between network segments

two。 In order to achieve network-wide interconnection, it must be clear that the following two problem packets are forwarded or discarded by the router, depending on whether the entry corresponding to the destination address of the packet can be found in the routing table. The router can automatically generate routing entries for all directly connected network segments, and for those non-directly connected network segments, they need to be specified through static routes.

3. Therefore, in order to achieve network-wide interworking, each router must be assigned routing entries for all non-directly connected network segments.

Experimental environment

The three routers R1, R2 and R3 are interconnected in pairs, and each router is equipped with Loopback addresses to simulate the network environment.
