Scenario 5-3: IP Subnet Design with a Class C Network 331
Figure 5-44
Scenario 5-2 Network Diagram
Given the information in Figure 5-44 and Table 5-46, perform the following activities:
1
Determine all subnet masks that meet the criteria in the introduction to this scenario.
2
Choose a mask and pick enough subnets to use for the original topology (refer to
Figure 5-44).
3
Create IP-related configuration commands for each router.
Scenario 5-3: IP Subnet Design with a Class C Network
Your job is to plan yet another network. The topology required includes four sites, one Ethernet
at each site, and partially meshed Frame Relay for connectivity, as shown in Figure 5-45. The
number of subnets will never grow. Choose a mask that will maximize the number of hosts per
Table 5-46
