What happens immediately after two OSPF routers have exchanged hello packets and have formed a neighbor adjacency?

  • They exchange DBD packets in order to advertise parameters such as hello and dead intervals.
  • They negotiate the election process if they are on a multiaccess network.
  • They request more information about their databases.
  • They exchange abbreviated lists of their LSDBs.

Explanation: During the exchange of hello packets, OSPF routers negotiate the election process and set the OSPF parameters. DBD packets are exchanged after that step has been completed. DBD packets contain abbreviated lists of link-state information. After that information has been exchanged, OSPF routers exchange Type 3 LSR packets to request further information.
