Hello Again, Neighbor!
Phani Raj Tadimety · Apress eBooks · 2015
The first step in exploring one’s area of residence is to get to know the immediate neighborhood. OSPF uses its Hello protocol as the way a router discovers and maintains its neighborly relationships across its links. As described in Chapter 9 , the router sends “Hello” packets to its neighbors, and in turn receives their response “Hello” packets. This chapter undertakes a deeper study of that Hello protocol.
