router adjacency & neigbourship

what is the difference between neigbourship & adjacency between 2 routers

[B.kablawi90]

Hi,

neigbourship refers to the connected routers for example Router1 is the neighbor of Router2 and vice versa.

adjacency refers to the status of  connected neighbor, so when the neighbors got adjacent based-on the adjacency parameters then they can exchange routes.

in another words, neighbors are simply routers that sit on the same segment and hear each other, but they do not engage in any closer cooperation. adjacent routers exchange routing information.

Stop spamming the forum with single-topic threads.  Put all your questions in one big thread. 

Specify the purpose of the questions if they are for school work or otherwise.  The reason behind this are two-folds: 

1.  A professor or instructor can tell if the answer is copied somewhere and may he/she might find ways to verify if you are a "hidden genius" or a plagerist. 

2.  What happens in the "wild" and what happens behind text books are two different things:  Text books might give you what happens in an "ideal world" and this is what the instructor wants.  If he/she finds answers that do not comply with text book materials one might not like the grades handed back.
