used to confirm receipt of certain types of OSPF packets

used to establish and maintain adjacency with other OSPF routers

used to request more information about any entry in the BDR

used to announce new OSPF information and to reply to certain types of requests

the same process ID

the same area ID

network addresses and wildcard masks

the same router ID

the same loop back address
