Configuration Exercises

1: Table 9.13 shows the interfaces and addresses of 14 routers. Also shown is the OSPF area to which each interface is connected. The following facts apply:

  • All interfaces of each router are shown in the table.

  • If no area is shown (-), OSPF should not be running on the associated interface.

  • The second octet of the subnet address is the same as the area ID.

  • The first 16 bits of the address of every OSPF interface are specific to the area. For example, addresses with the prefix 10.30.x.x will be found only within area 30.

Write OSPF configurations for the routers in Table 9.13. (Tip: Draw a picture of the routers and subnets first.)
