OSPF stands for open shortest path first. OSPF is an exterior routing protocol. OSPF uses Path vector routing algorithm.
CCNA Guide to Cisco Networking Fourth Edition Ch.8 Answer: OSPF is configured using the router ospf [process id] command.
Open standard protocols: Rip or OSPF. They are not Cisco proprietary protocols.
In OSPF, a topology database is a data structure that each router maintains to store information about the network topology within an OSPF area. It includes details such as the network links, their costs, and the routers connected to those links. This database is used to calculate the best routes for routing packets through the network.

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)
Bandwidth
OSPF LSA throttling helps the dampening of LSA updates in OSPF during times of network instability.
OSPF uses the path cost metric to determine the best route to a destination network. The path cost is based on the bandwidth of the link. Lower path costs indicate faster or more desirable paths.
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.

The root cost represents the cumulative cost of reaching a destination in a network, based on the metrics assigned to the paths leading to that destination. It is typically used in routing protocols like OSPF and EIGRP to determine the best path to reach a specific network based on the lowest accumulated cost.
