General Mechanism: i) Hello Packets: Used in order to establish relationships with the neighboring routers in a topology. On multi-access segments ad point-to-point segments, the default time to send hello packets is every 10 seconds and for non-broadcast multi-access (NMBA) segments like frame relay, the default time is every 30 seconds. ii) Dead Intervals: Wait period for an OSPF router before termination the relationship with its neighbor is called as Dead interval and is 4 times the hello interval. iii) Router Id: Identification of each OSPF router in an OSPF routing domain is exclusively by the router id. OSPF router can chose highest IP address of its loopback interface incase router id is not configured. IP address will be chosen by the OSPF router of any of its physical interfaces in absence of loopback interfaces. iv) Area Id: In OSPF routing domain the areas are defined as backbone routers also known as area 0, area border routers (ABR), which connect the backbone routers to any other areas in the OSPF routing domain and autonomous system border routers (ABSR), which are located between OSPF autonomous system and non-OSPF autonomous system.

All OSPF routers in the same routing domain must receive and maintain the same link-state information. OSPF routing domain must be designed with a backbone area and all the other areas should be
