addresses will be needed for each of the LAN interfaces.
How many subnets are needed?
9
1.
What is the maximum number of IP addresses that are needed for a single subnet?
51
2.
How many IP addresses are needed for each of the Branch1 LANs?
21
3.
How many IP addresses are needed for each of the Branch2 LANs?
13
4.
How many IP addresses are needed for each of the WAN links between routers?
2
5.
What is the total number of IP addresses that are needed?
176
6.
What is the total number of IP addresses that are available in the 192.168.1.0/24 network?
254
7.
Can the network addressing requirements be met using the 192.168.1.0/24 network?
yes
8.
Task 2: Design an IP Addressing Scheme
Determine the subnet information for the largest network segment or segments.
Step 1.
In this case, the two HQ LANs are the largest subnets.
How many IP addresses are needed for each LAN?
51
1.
What is the smallest-size subnet that can be used to meet this requirement?
/26
