Scenario

Refer to Figure 6-14, and design the addressing scheme for the network. After this is designed, write the configuration for the central router.

Ensure that you include the following:

1 Address the network using the private network 10.0.0.0. Design the addressing scheme so that it allows for the summarization of addresses between areas. Show the summarization that you allocate, and explain your reasons for your choices.

Area 0 is using a prefix of 28 bits within the area.

Area 2 is using a prefix of 22 bits within the area.

Area 3 is using a prefix of 24 bits within the area.

Area 4 is using a prefix of 30 bits for the serial connections. It is using a 28-bit prefix for the connections to the Ethernet routers. Do not include the subnets attached to the LANs in Area 4.

2 Issue the commands for the main router Figure 6-14 to configure the following:

— The network commands to place the appropriate interfaces into the correct areas

— The configuration of the totally stubby area (Area 4)

— The configuration of the stub (Area 4)

— Summarization between areas

— The election of the central router as designated router, where appropriate
