JN0-649 · Question #141
You are implementing the route summarization feature of OSPF. Which two results do you achieve in this scenario? (Choose two.)
The correct answer is B. It reduced the routing table size, enabling devices to store and process less information. C. It reduces the impact of topology changes on a device. OSPF inter-area route summarization reduces the routing information exchanged between areas and the size of routing tables, and improves routing performance. OSPF inter-area route summarization enables an ABR to summarize contiguous networks into a single network and advertise…
Question
You are implementing the route summarization feature of OSPF. Which two results do you achieve in this scenario? (Choose two.)
Options
- AIt helps in migrating to future multi-area OSPF network designs.
- BIt reduced the routing table size, enabling devices to store and process less information.
- CIt reduces the impact of topology changes on a device.
- DIt provides optimal routing in the network.

Explanation
OSPF inter-area route summarization reduces the routing information exchanged between areas and the size of routing tables, and improves routing performance. OSPF inter-area route summarization enables an ABR to summarize contiguous networks into a single network and advertise the network to other areas.
