Consider the topology shown in Fig.1 Denote the three subnets with hosts (starting clockwise at 12:00) as Networks A, B, and C Denote the subnets without hosts as Networks D, E, and F i. Assign network address to each of these six subnets, with the following constrain- sts: All addresses must be allocated from 214.97.254/23; Subnet A should have enough addresses to support 250 interfaces; Subnet B should have enought address to support 120 interfaces; and Subnet C should have enough addresses to sup- port 120 interfaces. Of course, subnet D, E and F should each be able to support two interfaces. For each subnet, the assignment should take the form a.b.c.d/x or a.b.c.d/x-e.f.g.h/y ii. Using your answer to part (a), provide the forwarding tables (using longest prefix matching) for each of the three routers
