what is the main features of link state routing protocols?..

Answer / vikramsingh11

Link-state algorithms are also known as Dijkstras algorithm
or as SPF (shortest path first) algorithms.

Link-state routing algorithms maintain a complex database of
topology information.

The distance vector algorithm are also known as Bellman-Ford
algorithms. They have nonspecific information about distant
networks and no knowledge of distant routers.

A link-state routing algorithm maintains full knowledge of
distant routers and how they interconnect. Link-state
routing uses:

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
The shortest path first (SPF) algorithm is a calculation
performed on the
database resulting in the SPF tree.

Hi Jitendera, I need ur suggestion. I completed my CCNA certification & also hving some sort of real time experience. Now i m planning to do CCNP. Little bit confusion is that whether it wud be better for me to go for CCNP ya CCNA (Security). As off my goal is to reach CCIE (Security & Switching/Routing). So tell me some solution of my confusion yaar..!!! Thanx & Regards Shahin..

Which statement about Ethernet switches is true? A. Symmetric switching allows connection between pods of unlike bandwidth and does not require memory buffering B. Memory Buffering is used to prevent a bottleneck when pods of different bandwidth are connected on a symmetric switch C. The latency can be reduced if the switch utilizes the store and forward method of switching store and forward is better for error detection D. The cut through method of switching is faster because the switch forwards the packet to the destination as soon as it reads the destination address
