Why do link-state protocols converge faster than most distance vector protocols?
Distance vector protocols compute their routing tables before sending routing updates; link-state protocols do not.
What is associated with link-state routing protocols?
shotrest path first calculation
What is one fundamental difference between distance vector routing protocols and link state routing protocols?
Distance vector protocols exchange their routing tables, and add a metric to each route. Link-state routing protols exchange topology information, then calculate the routes. As a result, there are the following fundamental differences:The information that is exchanged - routing table vs. topology information.Link-state protocols know the topology of the network (or an area); distance vector routing protocols don't.When the best route is calculated: in distance-vector routing protocols, a metric is added while the route is propagated from router to router. In link-state protocols, the best route is calculated separately by each router, only after having complete topology information.
What two names refer to the same algorithm used by all link-state routing protocols?
Link-state routing algorithms, also known as shortest path first (SPF) algorithms.
Which algorithm is run by link-state routing protocols to calculate the shortest path to destination networks?
Dijkstra
Is OSPF a classful or classless link-state routing protocol?
OSPF is a classless link-state routing protocol. RIP version 1 and IGRP are both classful distance vector routing protocols, EIGRP is a hybrid protocol that supports classless addressing.
How are LSAs used to manage updates to the routing topology in a link state protocol environment?
Link-state advertisements (LSAs) -- A link-state advertisement (LSA) is a small packet of routing information that is sent between routers.Topological database -- A topological database is a collection of information gathered from LSAs.SPF algorithm (Dijkstra algorithm) -- The shortest path first (SPF) algorithm is a calculation performed on the database resulting in the SPF tree.Routing tables -- A list of the known paths and interfaces.Link State Routing Protocols converge more quickly and they are less prone to routing loops than Distance Vector algorithms. On the other hand, Link State Routing Protocols require more CPU power and memory than distance vector algorithms. Link State Protocols use a hierarchical structure that limits the distance that a Link-State Advertisement (LSA) need to travel. Link State Protocols use multicasts to share the routing information. Only the routers which run Link State protocol only process the updates. Link State routers send updates only when there is a change in the state of the network (incremental updates).
What information is contained in LSPs sent by link-state protocols that is not included in distance vector routing protocol updates?
The state of directly connected links
What feature do modern link-state protocols provide to minimize processing and memory requirements?
splitting routing topologies into smaller areas
What describes the process that routers use within a network to learn each other's routes?
routers use routing protocols to exchange routing information. check out the link below for lots of information on routing protocols.
What are the two most commonly encountered link-state routing protocols in ip network?
Routers that run a link-state protocol can establish a complete topology of the network. The shortest path first algorithm is used.
What information is contained in LSPs sent by link-state protocols over distance vector protocols?
I think the answer is the state of each directly connecyed link.
