For REMOTE, begin with the 10.0.32.0 address as the subnet for loopback 0. What subnet mask
would you use to provide enough space for 2000 users while maximizing the number of subnets?
255.255.248.0 or /21
Starting with 10.0.32.0, contiguously assign the next three subnets, all supporting 2000 hosts. List all
four subnets here.
10.0.32.0/21
10.0.40.0/21
10.0.48.0/21
10.0.56.0/21
Now pick a WAN subnet for the link shared by HQ and REMOTE. List the subnet you assigned here.
Can be any subnet /30 from the 10.0.0.0/21 address space.
Label the topology in Figure 9-11 with the networks and finish filling in the IP address table in Table
9-7 with your chosen addressing scheme. Use the first available IP address in each subnet as the inter-
face address. For the WAN subnet, assign HQ the first address.
