Consider a network with three routers R1, R2, and R3. Each router is connected with the two other routers. Router R1 is also connected to a subnet A, R2 is also connected to a subnet B, and R3 is also connected to a subnet C.

1. How many subnets exist in this network? (Hint: the correct answer is NOT three)

2. Assign network addresses to each subnet. All addresses must be allocated from the 214.97.254/23 address block. Subnet A should have enough addreses to support 250 interfaces. Subnet B should have enough addresses to support 120 interfaces. And Subnet C should have enough addresses to support 120 addresses. For each subnet, you should show the assigned addresses as a prefix (e.g., a.b.c.d/x). Keep in mind though that a certain subnet may use a prefix that is contained in another subnets prefix.

3. Based on your previous answer, show the forwarding tables for each of the three routers.
