RIP and a Strangely Configured Subnet. (Problem #65)
Here is a problem that is not quite a practical situation perhaps but one that allows itself to be solved with the facilities provided by Cisco IOS.
Consider the network represented in the figure above. (Click on the image to see a larger and readable rendering.) Note that the addressing on the ethernet subnet is strange in that the ethernet interface on router R3 is configured to be in a different subnet compared with the ethernet interfaces on routers R1 and R2. The three routers are also configured with loopback interfaces with addresses as indicated in the figure.
Your task in this problem is to turn on RIP routing between the three routers and allow each router to ping the loopback interfaces on the other two routers without modifying the interface addresses on any router.
