BFD for OSPF refers to the association of BFD with OSPF to speed up OSPF's response to network topology changes. The OSPF neighbor relationship can enter the Full state only after the BFD session goes up. The OSPF neighbor relationship can go down only after the BFD session goes down.
정답: B
On the OSPFv3 network shown in the figure, the LSDB of R2 contains ____ Router-LSAs. (Enter only digits.)
정답:
3
Explanation:
To determine the correct answer, we need to analyze how OSPFv3 handles Router LSAs (Type 1 LSAs) in a simple Area 0 topology like the one shown in the figure.
1. Understanding OSPFv3 Router LSAs (Type 1 LSAs)
* Router LSAs (Type 1 LSAs) are generated by each router within an OSPF area to describe its own directly connected links.
* Each router in an OSPF area generates exactly one Type 1 LSA.
* The Link-State Database (LSDB) on a router contains LSAs from all routers in the same area.
2. Analyzing the Network in the Figure
* There are 3 routers: R1, R2, and R3.
* All routers are in OSPFv3 Area 0 (which is a single area).
* Each of these routers generates one Router LSA (Type 1 LSA).
* Since R2 is in the same area as R1 and R3, its LSDB contains the Router LSAs from itself, R1, and R3.
3. Conclusion
* The LSDB of R2 contains 3 Router LSAs (one from each router: R1, R2, and R3).
* Final Answer: 3

On the OSPF network shown in the figure, area 1 is an NSSA, area 2 is a common area, and R4 imports an external route 10.0.4.4/32. The router ID of each router is 10.0.X.X, where X is the router number. If the asbr-summary 10.0.4.0 255.255.255.0 command is run in the OSPF processes of R1 and R3, which of the following routers have the route 10.0.4.0/24 in their routing tables?
