LAB: Network Summary LSAs

He're you'll be examing the Type-3 LSA in detail.

  1. How many Network Summary LSAs are present in the 101.101.101.101 area?
  2. How many Network Summary LSAs are present in the backbone area?
  3. Are there any Network Summary LSAs that match any of the networks present in your Router LSA for the backbone area?
  4. How many Network Summary LSAs are present in the unique area that is attached to each router (0.0.0.1, 0.0.0.2, or 0.0.0.3)?
  5. Are there any Network Summary LSAs that match any of the networks present in your Router LSA for the 101.101.101.101 area?
  6. Summarize to the full extent possible all of the networks in the 0.0.0.1, 0.0.0.2, and 0.0.0.3 networks
  7. Find the route that matches your summarized network in the routing table
  8. Examine the Network Summary LSA that your router is using to coalesce routes
  9. Compare the Metric of the LSA to the costs your router has for the networks being summarized
  10. Set the metric of your summarized route to a value of 5000
  11. How many Network Summary LSAs are present in the 101.101.101.101 area?
  12. How many Network Summary LSAs are present in the backbone area?
  13. Block the 10.102.0.0/24 network in area 102.102.102.102 from being advertised into the backbone or any other areas
  14. Attempt to summarize all of the 10.101/16 address space in the backbone as it is advertised into the other areas. Why didn't it work?
