OSPF stands for open shortest path first. OSPF is an exterior routing protocol. OSPF uses Path vector routing algorithm.

What command injects a default route into an OSPF network?
CCNA Guide to Cisco Networking Fourth Edition Ch.8 Answer: OSPF is configured using the router ospf [process id] command.
Which internal routing protocol would use if you needed to route between Cisco and non-Cisco equipment?
Open standard protocols: Rip or OSPF. They are not Cisco proprietary protocols.
What are the three router roles in an OSPF network?
Designated router, the backup designated router, and the DROTHER Internetworking with Cisco and Microsoft Technologies pg. 306-307
What does DR and BDR stand for in Cisco IOS?
A DR and BDR in a Cisco network stands for Designated Router and Backup Designated Router. These designations are used when working with certain routing protocols such as Open-Shortest Path First (OSPF)
What factor does the Cisco implementation of OSPF use to pick the best route?
Bandwidth
What is ospf throttle?
OSPF LSA throttling helps the dampening of LSA updates in OSPF during times of network instability.
Should EIGRP only be run on networks with Cisco equipment?
EIGRP is a Cisco proprietary routing protocol and therefore can only be used with Cisco routers.You can do route redistribution on Cisco routers, this allows you to take routes from another routing protocol (such as OSPF or RIP) and place them into the EIGRP network that way downstream nodes can be informed of routes available.
How many network types available in OSPF?
3 types off network are availble
How many types of LSAs does OSPF support?
5 types Internetworking with Cisco and Microsoft Technologies pg. 307
What are the key characteristics of OSPF?
OSPF has the following features:Fast Convergence OSPF can detect and propagate topology changes faster than RIP. Count-to-infinity does not occur with OSPF.Loop-Free Routes OSPF-calculated routes are always loop-free.Scalability With OSPF, an AS can be subdivided into contiguous groups of networks called areas. Routes within areas can be summarized to minimize route table entries. Areas can be configured with a default route summarizing all routes outside the AS or outside the area. As a result, OSPF can scale to large and very large internetworks. In contrast, RIP for IP internetworks cannot be subdivided and no route summarization is done beyond the summarizing for all subnets of a network ID.Subnet Mask Advertised with the Network OSPF was designed to advertise the subnet mask with the network. OSPF supports variable-length subnet masks (VLSM), disjointed subnets, and supernetting.Support for Authentication Information exchanges between OSPF routes can be authenticated.Support for External Routes Routes outside of the OSPF AS are advertised within the AS so that OSPF routers can calculate the least cost route to external networks.
At what layer in the osi model would you find protocols such as rip and ospf?
OSPF and RIP are used in the network layer of the ISO model.
What are required when adding a network to the OSPF routing process configuration?
network address wildcard mask area ID
