Consider the following network that consists of four subnets with hosts and one point to point link interconnected by two routers. The number of hosts for the subnets are indicated in the figure. Suppose static IP addresses will be assigned to these hosts and the router interfaces from IP address block 144.122.0.0/21. a. Identify the subnets in the network and assign network addresses to the subnets in the form a.b.c.d/m such that each subnet has enough number of IP addresses and the largest possible value is assigned to m. b. Give forwarding tables in R1 and R2 to enable proper routing between the hosts in the network. c. We are planning to attach a new subnet, namely Subnet 5, to R2 and the addresses will be assigned to this subnet from remaining addresses of the address block of the network. What would be the largest possible number of hosts that may be interconnected by this subnet and the corresponding subnet address/mask?

R1 R2 Subnet 1 1 500 hosts Point to Point Link Subnet 3 200 hosts Subnet 2 500 hosts Subnet 4 200 hosts
