OSPF neighbors are said to have reached the "Two-way" state when they are both aware of each other. But, how does each one indicate that it is aware of the other?
What you'll learn from this video:
In this animation, we see how, within the exchange of 3 packets, two newly connected routers can reach a two-way neighbour relationship. The key is that OSPF hello packets contain a list of the Router IDs of neighbors that the sending router has recently received valid Hellos from. So, each router can see itself the other router's list of neighbours.
