Problem description:

We have been given network 198.32.128.0/22. We need to subnet it such 
that we can support:

At Site A
	One network with 280 endstations
	One network with 40 endstations
	One network with 90 endstations

At site B 
	One network with 200 endstations

Site A connects to the Internet with a serial link also.

Site A links to Site B with a point to point serial link.

We have 2 routers with two serial interfaces (ser0, ser1)
and one Gigabit ethernet interface (Gi0/0)

We have 1 router with 3 ethernet interfaces (eth0, eth1, eth2)

We have any number of 96, 48, 24 or 16 port ethernet switches.







Subnet/address assignments:

At Site A
	198.32.128.0/23	- supports 512 addresses (510 usable)
		198.32.129.254 is router1 address on this subnet (interface Gi0/0)
		198.32.129.253 is router2 address on this subnet (interface eth0)
		198.32.129.252 is a 96 port switch on this subnet
		198.32.129.251 is a 96 port switch on this subnet
		198.32.129.250 is a 96 port switch on this subnet
		198.32.129.249 is a 16 port switch on this subnet
		All other IP's are available for endstations.

	198.32.130.0/25 - support 128 addresses (126 usable)
		198.32.130.126 is router2 address on this subnet (interface eth2)
		198.32.130.125 is a 96 port switch on this subnet
		All other IP's are available for endstations.

	198.32.130.128/26 - support 64 addresses (62 usable)
		198.32.130.190 is router2 address on this subnet (interface eth1)
		198.32.130.189 is a 48 port switch on this subnet
		All other IP's are available for endstations.
			

At Site B
	
	198.32.131.0/24 - support 256 addresses (254 usable)
		198.32.131.254 is router3 address on this subnet (interface Gi0/0)
		198.32.131.253 is a 96 port switch on this subnet
		198.32.131.252 is a 96 port switch on this subnet
		198.32.131.251 is a 48 port switch on this subnet
		All other IP's are available for endstations.

Site A and Site B are linked together with

	198.32.130.192/30
		198.32.130.193 is router1 at site A address (interface ser1)
		198.32.130.194 is router3 at site B address (interface ser0)

Site A is connected to the internet via 65.1.1.0/30
		65.1.1.1 is the ISP address
		65.1.1.2 is router1 address (interface ser0)




Routers used:



Router1 - Site A 
	interface ser0 - 65.1.1.2/30 - link to Internet
	interface ser1 - 198.32.130.193/30 - link to Site B router 3
	interface Gi0/0 - 198.32.129.254/23 - link to network 198.32.128.0/23

Router2 - Site A
	interface eth0 - 198.32.129.253 - link to network 198.32.128.0/23
	interface eth1 - 198.32.130.190 - link to network 198.32.130.128/26
	interface eth2 - 198.32.130.126 - link to network 198.32.130.0/25

Router3 - Site B
	interface ser0 - 198.32.130.194/30 - link to Site A router 1
	interface ser1 - unused
	interface Gi0/0 - 198.32.131.254/24 - link to network 198.32.131.0/24
