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 three parameters must be identical between OSPF routers in order to form an adjacency?
area id hello interval network type
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 ospf throttle?
OSPF LSA throttling helps the dampening of LSA updates in OSPF during times of network instability.
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.
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.
