OSPF Problem 2

Try to solve the lab problem in 10 minutes or less.
  • Enable OSPF area 215 on the link of R1 in VLAN 215 (Fa0/1).
  • Enable OSPF area 27 on the link of R2 in VLAN 27 (Fa0/0).
  • Use ‘network‘ statement with wildcard mask that matches the network mask of the interface.

Extra Credit
Take as much time as you need to answer the following questions:
  1. What are the benefits of using OSPF multiple area topology?
  2. What do we call area 0 in OSPF multiple area topology?
  3. In the OSPF lab completed, what do you call R1 and R2 (routers connected to area 0 and other area)?
  4. What are LSA types: 1, 2, 3, 4, 5, 7 and what do they communicate in OSPF domain?
  5. What do we call an OSPF router whose all links belong to a single area?
  6. What do we call an OSPF router whose all links belong to an area 0?

When you have solved the problem check the hint(s) below:
