OSPF Neighbor States

I was kinda reviewing about OSPF and I thought writing what I have learned is a good idea for me to remember them.

Down State - This is the state of a neighbor in OSPF when the RouterDeadInterval expired and the router did not receive any hello packet from a certain router. When the router pings the neighbor in down state, it will not be successful

Init - This is the state of a neighbor when a router receives a hello packet within the last RouterDeadInterval but the hello packet doesnt contain the router id of the router. The router should be able to ping the neighbor that is in this state

2-way - This state will be achieved when a router receives a hello packet that contains its router id. This means that the bidirectional communication is already established.

(well, i think it's a bad idea. im lost for words. ehehehehe. anyway, these are the other neighbor states. don't worry i will finish them one these days...)
