GNS: OSPF Multi Area
A lot of people did like the early project: GNS: Routing redistribution example, so I decied to do another project, this one about OSPF Multi Area, subject suggested by a user at Linked In. Just like the previous project this subject is very important for those whishing todo the 642-901 (BSCI) test. A better understanding about stub areas, not so stub areas and virtual links are the main point of this project.
This is the scenary:
- Area 0: R1 and R2 (Area backbone)
- Area 1: R2 and R3 (Area configured as virtual link)
- Area 2: R3 and R4 (Area connected to ISP and nssa)
- Area 3: R1 and R5 (Area totally stub)
GNS: Route redistribution example
Nowadays I'm Cisco CCNA, and I plan to take the CCNP certification during this year. The first test I decided to do is the BSCI. A important topic for this test is route redistribution, so I made this GNS Project to explore some aspects of this feature, and I would like to share with anyone interested.
This is the scenario:
- Routers running RIP: R1, R2, R4 and R5
- Routers running OSPF (Area 0): R1, R3 and R5
- R1 has both routing protocols and it is the responsible to redistribute they.
- R4 and R5 are interconnected through RIP too, and the default behavior of R5 is try to reach R4's networks through OSPF routes (longer path), because OSPF has a better administrative distance than RIP.
