| 1: | Which command in OSPF shows the network LSA information? |
| 2: | What command would you use to create a totally stubby area? |
| 3: | What is a virtual link, and what command would you use to create it? |
| 4: | Where would you issue the command to summarize IP subnets? State the command that is used. |
| 5: | How would you summarize external routes before injecting them into the OSPF domain? |
| 6: | When is a virtual link used? |
| 7: | Give the command for defining the cost of a default route propagated into an area. |
| 8: | Give an example of when it would be appropriate to define a default cost. |
| 9: | On which router is the area default cost defined? |
| 10: | Give the command to configure a stub area and state on which router it is configured. |
| 11: | What is the purpose of the area range command, and why is it configured on the ABR? |
| 12: | Give the commands to configure a router to place subnets 144.111.248.0 through to 144.111.255.0 in Area 1 and to put all other interfaces into Area 0. |
| 13: | Give the syntax to summarize the subnets 144.111.248.0 to 144.111.254.255 into another autonomous system. |
| 14: | Explain briefly the difference between the area range command and the summary-address command. |
| 15: | Explain the following syntax and what it will achieve: area 1 stub no-summary . |
| 16: | Why would you configure the routing process to log adjacency changes as opposed to turning on debug for the same trigger? |
| 17: | Give some of the common reasons that neighbors fail to form an adjacency. |
| 18: | When configuring a virtual link, which routers are configured? |
| 19: | What does the command area 1 default-cost 15 achieve? |
