IERG 3310 Homework Assignment 3 1. (15 points) Consider a datagram network using 8-bit host addresses. Suppose a router uses longest prefix matching and has the following forward table: Prefi ... x Match Interface 00 0 010 1 011 2 10 2 11 3 For each of the four interfaces, give the associated range of destination host addresses and the number of addresses in the range. Destination Address Range Link Interface 2. (18 points) Consider the topology shown above. Denote the three subnets with hosts (starting clockwise at 12:00) as Networks A, B, and C. Denote the sub-nets without hosts as Networks D, E, and F. a. Assign network addresses to each of these six subnets, with the following constraints: All addresses must be allocated from 214.97.254/23; Subnet A should have enough addresses to support 250 interfaces; Subnet B should have enough addresses to support 120 interfaces; and Subnet C should have enough addresses to support 120 interfaces. Of course, subnets 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. [Show More]
