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.

What OSPF packets will trigger the reset of the Dead Time counter?
packets
Compare and contrast the advertisements by RIP and OSPF?
RIP is an Interior Gateway Protocol and the most widely accepted routing protocol. It is also known by the name of the Unix daemon program routed. RIP is straightforward: it arranges to have routers to broadcast their entire current routing database periodically OSPF is a link-state algorithm. OSPF specifies a class of messages called link-state advertisements (LSAs) that allow routers to update each other about the LAN and WAN links to which they are connected. When a change is made to the network, LSAs flow between routers. OSPF routers receive link-state updates and store them in a topology database in memory. OSPF networks as an end-station-to-router protocol. OSPF addresses all the deficiencies of RIP, without affecting connectivity to RIP based networks.
What factor does the Cisco implementation of OSPF use to pick the best route?
Bandwidth
What is transit area in ospf?
Transit Area: area through which Virtual Links is configured
What is the maximum number of hops that OSPF allows before marking a network as unreachable?
255
Which ospf neighbor indicate that two neighbors are synchronized and have formed adjacencies?
Full
Which OSPF neighbor state indicates that two neighbors are synchronized and have formed adjacencies?
Full
Which two link state routing protocol challenges does OSPF resolve through the election of a DR?
the extensive flooding of LSAs throughout the OSPF areathe excessive adjacencies when the number of routers increases
What is the first step OSPF and IS-IS routers take in building a shortest path first database?
The first step OSPF and IS-IS routers take in building a shortest path first database is to exchange link-state advertisements (LSAs) or link-state packets (LSPs) with neighboring routers. These packets contain information about the router's directly connected neighbors and the state of their links.
What are two function of the routing engine in juniper?
To build OSPF and ISIS adjacencies. To verify that packets arriving at the router are allowed by any configured firewall filters.
What does OSPF use to reduce the number of exchanges of routing information in networks where large numbers of neighbors are present?
Within a network segment where a router may have several neighbors, such as an Ethernet network, the OSPF routers elect a designated router (DR). Due to the importance of the DR, a backup DR (BDR) is also elected. The DR will centralize communications - all other routers in that segment will only have a full adjacency with the DR and the BDR - and partial adjacencies with all other routers in the segment.
What is ospf throttle?
OSPF LSA throttling helps the dampening of LSA updates in OSPF during times of network instability.
What type of protocol is OSPF?
OSPF is short form of open shortest path first. OSPF is based on linked state routing.
What type of routing protocol is OSPF?
OSPF is short form of open shortest path first. OSPF is based on linked state routing.
Which is classified as a link-state routing protocol?
There are actually two OSPF and IS-IS
What does the Cisco IOS use to calculate the OSPF cost to a destination network?
OSPF stands for open shortest path first. OSPF is an exterior routing protocol. OSPF uses Path vector routing algorithm.
Why we r using rip instead of ospf?
Could be because your routers do not support OSPF.
