Two routers need to be configured within a single ospf area which two components need to be configured on both the routers to achieve this?
Two routers need to be configured within a single OSPF area. Which two components need to be configured on both routers to achieve this?
What are OSPF Databases?
A "database" is a collection of information, often organized in tables. OSPF routers - i.e., routers that implement the OSPF routing protocols - need to maintain several databases, for example, a neighbor database (a list of connected neighbors), and a link-state database (a list of all the connections between different routers in the same area, which the router has learned about).

What three parameters must be identical between OSPF routers in order to form an adjacency?
area id hello interval network type
Why do all routers in a stub area need to know that the area is a stub?
So that way all routers in the area know to neither accept, nor generate External (Type 5) LSA's. Additionally, one of the rules of an OSPF area is that all routers in that area must have an identical topology database. If one router is not configured as stub and accepts, or generates an External LSA, then that rule is broken, as the non-stub router will have the external LSA, and the other's will not.

What is the difference between OSPF and IS-IS and which one is preferred?
OSPF requires an area 0, while IS-IS does not. Like OSPF, IS-IS uses areas when designing the network. However, IS-IS does not require and area 0 like OSPF does. Because IS-IS was originally designed for non-IP protocols, it can more easily support IPv6 routing. Preference is relative to the size of the network. OSPF (a network layer protocol) is more often used in medium to large enterprise networks because of it's special tunnelling features. IS-IS is often used in VERY large ISP networks because of its stability features and the fact that it can support more routers.
What parameters must be indentical between OSPF routers in order to form an adjacency?
Area ID Timers Stub Flag Subnet Mask (excluding virtual links and Point-to-point links) and MTU are also important.

What is transit area in ospf?
Transit Area: area through which Virtual Links is configured
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.
A large corporation that frequently integrates networks from newly acquired businesses has just decided to use ospf as the corporate routing protocol instead of eigrp what two benefits will the change?
the ability to support multi-vendor routers the ability to create a hierarchical design using area
