The Hello packet (v3)

Hello packets are OSPF packet type 1. These packets are sent periodically on all interfaces (including virtual links) in order to establish and maintain neighbor relationships. In addition, Hello packets are multicast on those links having a multicast or broadcast capability, enabling dynamic discovery of neighboring routers.

All routers connected to a common link must agree on certain parameters (HelloInterval and RouterDeadInterval). These parameters are included in Hello packets allowing differences to inhibit the forming of neighbor relationships. The Hello packet also contains fields used in Designated Router election (Designated Router ID and Backup Designated Router ID), and fields used to detect bidirectional communication (the Router IDs of all neighbors whose Hellos have been recently received).
