In-Depth Information
Can the Branch 3 and Branch 4 networks be summarized into one route on the East router? This sum-
marized route should also include the serial link that connects the Branch 3 and Branch 4 routers.
yes
What would be the command to add this summary route to the routing table? Use the S0/0/1 interface
of the East router as the exit interface.
ip route 172.16.24.0 255.255.248.0 serial 0/0/1
The Branch 1 router requires a static route for traffic destined for Branch 2. All other traffic should be
sent to the West router using a default static route. What commands would be used to accomplish this?
ip route 172.16.4.0 255.255.254.0 serial 0/0/1
ip route 0.0.0.0 0.0.0.0 serial 0/0/0
The Branch 2 router requires a static route for traffic destined for Branch 1. All other traffic should be
sent to the West router using a default static route. What commands would be used to accomplish this?
ip route 172.16.2.0 255.255.254.0 serial 0/0/1
ip route 0.0.0.0 0.0.0.0 serial 0/0/0
The Branch 3 router requires a static route for traffic destined for Branch 4. All other traffic should be
sent to the East router using a default static route. What commands would be used to accomplish this?
ip route 172.16.30.0 255.255.254.0 serial 0/0/1
ip route 0.0.0.0 0.0.0.0 serial 0/0/0
The Branch 4 router requires a static route for traffic destined for Branch 3. All other traffic should be
sent to the East router using a default static route. What commands would be used to accomplish this?
ip route 172.16.28.0 255.255.254.0 serial 0/0/1
ip route 0.0.0.0 0.0.0.0 serial 0/0/0
Lab 3-3: Subnetting Scenario 3 (3.5.4)
Instructor note:
This lab is impossible to complete with fixed-length subnet masking. Use this lab as a scaf-
folding exercise to link the student to the concept of VLSM, which is discussed in Chapter 6, “VLSM and
CIDR.” Avoid offering the student any help in solving the problem of not having enough address space.
Upon completion of this lab, you will be able to
Determine the number of subnets needed
■
Determine the number of hosts needed
■
Design an appropriate addressing scheme
■
Conduct research to find a possible solution
■
Scenario
In this lab, you have been given the network address 192.168.1.0/24 to subnet and provide the IP
addressing for the network shown in Figure 3-5. The network has the following addressing requirements:
