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.
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 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.
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
Why we r using rip instead of ospf?
Could be because your routers do not support OSPF.
What is OSPF adjacencies?

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.
