Homework 2

You will draw a physical and logical daigram for a network which is 64.44.120.0/22 We have 4 internal subnets at two sites. Net1 needs to support 190 hosts but may later grow to 400 hosts. Net2 needs to support 76 hosts but may later grow to 200. Net3 needs to support 14 hosts but may grow to 100 hosts. Net4 has 10 hosts but might grow to 40 hosts. We also may have unused address space You have available 4 routers. 
	border router (brouter) has three interfaces
		se0	
		Gi0/0
		Gi0/1

	internal router 1 (irouter1) has two interfaces
		Gi0/0
		Gi0/1

	internal router 2 (irouter2) has two interfaces
		eth0	
		eth1

	internal router 3 (irouter3) has three interfaces
		se0	
		gi0/0	
		gi0/1
You also have available any number of 8, 16, 32, 48, and 96 port 10/100/1000 managable ethernet switches.

Your site connectes via a border router to the Internet via 66.44.1.0/30 using point to point serial interface, se0. The ISP is at 66.44.1.1 the border router address for interface se0 on that point to point is 66.44.1.2.

Site A links to Site B via 64.44.123.0/30. .1 is internal 1 router at site A and .2 is internal router 3 at site B.

To do this you have decided to subnet 64.44.120.0/22 as such 

	64.44.120.0/23 - Net1
	64.44.122.0/24 - Net2
	64.44.123.0/30 - Link from Site A to Site B
	64.44.123.4/30 - (reserved for future growth)
	64.44.123.8/29 - (reserved for future growth)
	64.44.123.16/28 - (reserved for future growth)
	64.44.123.32/27 - (reserved for future growth)
	64.44.123.64/26  - Net4
	64.44.123.128/25 - Net3
and assigned the following IP addresses to the interfaces on the four routers: 

	border router (brouter) has 3 interfaces
		se0	64.44.1.2/30
		Gi0/0	64.44.121.254/23
		Gi0/1	64.44.123.254/25
	internal router 1 (irouter1) has three interfaces
		se0	64.44.123.1/30
		Gi0/0	64.44.121.253/23
		Gi0/1	64.44.122.254/24
	internal router 2 (irouter2) has two interfaces
		eth0	64.44.123.253/25
		eth1	64.44.122.253/24
	internal router 3 (irouter3) has two interfaces used
		se0	64.44.123.2/30
		Gi0/0	64.44.123.126/26
The border router (brouter) has 2 ethernet interfaces. One, Gi0/0, connects to and instantiates the 64.44.120.0/23 subnet. The other, Gi0/1, connects to and instantiates the 64.44.123.128/25 subnet. It uses the address 64.44.121.254/23 for Gi0/0 and 64.44.123.254/25 for Gi0/1.

A internal router (irouter1) is connected to 64.44.120.0/23 via its interface Gi0/0 and also connects the 64.44.122.0/24 network via its interface Gi0/1. It also has a serial interface connected to site B (se0) It uses 64.44.121.253 for Gi0/0 and 64.44.122.254 for Gi0/1 and 64.44.123.1 for the se0 link.

A internal router (irouter2) is conected to both 64.44.123.128/25 via its eth0 interface and 64.44.122.0/24 via its eth1 interface. It uses 64.44.123.253 for eth0 and 64.44.122.253 for eth1.

A internal router (irouter3) is at site B and is connected to 64.44.123.64/26 via its interface Gi0/0. It also has a serial interface connected to site A (se0) It uses 64.44.123.126 for Gi0/0 and 64.44.123.2 for the se0 link.
