The first is that the protocol is open, which means that its specification is in the public domain. The OSPF specification is published as Request For Comments (RFC) 1247. The second principal characteristic is that OSPF is based on the SPF algorithm, which sometimes is referred to as the Dijkstra algorithm (Answer is from CCNA 3 guide)
What else can I help you with?
Which is classified as a link-state routing protocol?
There are actually two OSPF and IS-IS
Which two of these are routing protocol?
Rip ospf
What is OSPF adjacencies?
OSPF is a link-state routing protocol that helps Routers exchange IP routes. OSPF Adjacencies is the established "neighborship" between two OSPF routers in order to make the exchange of routes. In this case, Adjacency means the same as "peering", that the OSPF speakers (routers) are able to "talk" to each other.
Which two commands can be used to modify the default OSPF metric calculation of a link?
The "ip ospf cost" command can be used to manually set the cost of an OSPF-enabled interface. The "bandwidth" command can indirectly affect OSPF metric calculation by adjusting the bandwidth on an interface, which in turn affects the OSPF metric calculation.
List two layer 3 Protocols?
ospf, bgp
Which ospf neighbor indicate that two neighbors are synchronized and have formed adjacencies?
Full
What is ospf throttle?
OSPF LSA throttling helps the dampening of LSA updates in OSPF during times of network instability.
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 type of protocol is OSPF?
OSPF is short form of open shortest path first. OSPF is based on linked state routing.
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.
What are the characteristics of OSPF areas?
It provides fast network convergence. It transmits route updates throughout a network using IP-based multicasting.
What type of routing protocol is OSPF?
OSPF is short form of open shortest path first. OSPF is based on linked state routing.
