HW4 Problem 1 Consider a datagram network using 8-bit host addresses. Suppose a router using longest prefix matching has the following forwarding table Prefix Interface 010 2 otherwise 3 For each of the four interfaces, give the associated range of destination host addresses and the number of addresses in the range Problem 2 Consider an ISP that owns the block of addresses in 123.119.14.64/26. Suppose it wants to create three subnets, where Subnet l supports at least 30 interfaces, Subnet2 supports at least 12 interfaces, and Subnet3 supports at least 9 interfaces. Provide the network addresses (of the form a.b.c.d/x) of the three subnets that satisfy these requirements. Problem 3 Consider the network shown in Figure 1 223.1.1 11.4 Router 1 223.1.9 23.1.7.0 SubnetD 223.1.9 Router 2 Router 3 3.27 223.1 122 223.1 132 Figure 1. Illustration for Problem 3 a) Give the network addresses of Subnets A, B, and C in the Subnet B supports 16 interfaces, Subnet C supports 32 b) Using answer to a), provide the forwarding tables (each form of a.b.c.d/x, such that: Subnet A supports 8 interfaces, interfaces
