What are reasons for creating OSPF in a hierarchical design? To decrease routing overhead To speed up convergence To confine network instability to single areas of the network To make configuring OSPF easier

1, 2 and 3
3 only
3 and 4
2, 3 nd 4

Correct Answer: 1, 2 and 3

Explanation:

OSPF is created in a hierarchical design, not a flat design like RIP. This decreases routing overhead, speeds up convergence, and confines network instability to a single area of the network.

More Questions from EIGRP and OSPF

Which is true regarding EIGRP successor routes? A successor route is used by EIGRP to forward traffic to a destination. Successor routes are saved in the topology table to be used if the primary route fails. Successor routes are flagged as "active" in the routing table. A successor route may be backed up by a feasible successor route. Successor routes are stored in the neighbor table following the discovery process.
With which network type will OSPF establish router adjacencies but not perform the DR/BDR election process?
You need the IP address of the devices with which the router has established an adjacency. Also, the retransmit interval and the queue counts for the adjacent routers need to be checked. What command will display the required information?
You get a call from a network administrator who tells you that he typed the following into his router: Router(config)#router ospf 1 Router(config-router)#network 10.0.0.0 255.0.0.0 area 0 He tells you he still can't see any routes in the routing table. What configuration error did the administrator make?
Which command will display all the EIGRP feasible successor routes known to a router?
