You have been hired by a small school
system in York, AL. You are to maximize a full Class C address using
IP unnumbered and VLSM. You only have one Class C for this network
setup.
From the "Router A" console
- Cable the lab as shown above and
erase all routers.
- To configure the interfaces and
turn on the EIGRP routing protocol issue the following commands:
- router-a(config)#interface
fastethernet 0/0
- router-a(config-if)#ip
address 206.202.19.97 255.255.255.224
- router-a(config-if)#no
shutdown
- router-a(config-if)#interface
serial 0/0
- router-a(config-if)#ip
address 206.202.19.89 255.255.255.252
- router-a(config-if)#no
shutdown
- router-a(config-if)#router
eigrp 83
- router-a(config-router)#network
206.202.19.0
- router-a(config-router)#no
auto-summary
- router-a(config-router)#^Z
From the "Router B" console
- Issue the following
commands:
- router-b(config)#interface
fastethernet 0/0
- router-b(config-if)#ip
address 206.202.19.81 255.255.255.248
- router-b(config-if)#no
shutdown
- router-b(config-if)#interface
serial 0/0
- router-b(config-if)#ip
address 206.202.19.93 255.255.255.252
- router-b(config-if)#clockrate
56000 router-b(config-if)#no shutdown
- router-b(config-if)#interface
serial 0/1
- router-b(config-if)#ip
address 206.202.19.90 255.255.255.252
- router-b(config-if)#router
eigrp 83
- router-b(config-router)#network
206.202.19.0
- router-b(config-router)#no
auto-summary
- router-b(config-router)#^Z
- Follow the same
procedure with different addresses on the other two routers
From the "Router D" console
- Enter show
ip eigrp topology 206.202.19.0
and show ip route.

- Calculate the number of hosts on
each subnet by only using the routing table
