Which type of OSPF LSA(s) can be represented with the label O*E2 in a routing table?
- type 1 and type 2 LSAs
- type 3 and type 4 LSAs
- type 5 LSA only
- type 4 and type 5 LSAs
Explanation: Each router uses the SPF tree to determine the best paths to destination networks. The method that is used to calculate these paths is outlined below:
1. All routers calculate the best paths to destinations within their area, adding these entries to the routing table. They are the type 1 and type 2 LSAs, and are represented with a routing designator of O.
2. All routers calculate the best paths to the other areas within the internetwork. They are type 3 and type 4 LSAs, and are represented with a routing designator of O IA.
3. All routers (except those that are in a stub area) calculate the best paths to the external autonomous system (type 5) destinations. They are represented with either an O E1 or an O E2 route designator, depending on the configuration.
