Consider the network shown in Figure 1.

a) Give the network addresses of Subnets A, B, and C in the form of a.b.c.d/x, such that: Subnet A supports 8 interfaces, Subnet B supports 16 interfaces, Subnet C supports 32 interfaces.

b) Using answer to a), provide the forwarding tables (each row containing prefix match and outgoing interface fields) for each of the three routers. Suppose that no packet will have a router interface as the final destination. For the outgoing interface, you only need to specify which subnet the packet needs to be forwarded to (e.g., Router 1 can forward to Subnet A, Subnet D, Subnet F).
