OSPF Configuration Options
1)Enable OSPF (router ospf process-id)2)Enable OSPF on interfaces (network DDN WC_mask area area-id)3)Set Router ID (router-id DDN, or
interface loopback number) 4)Set Hello and Dead Intervals (ip ospf hello-interval number,
ip ospf dead-interval number)5)Tune OSPF metrics (ip ospf cost number, or
bandwidth number, or
auto-cost-reference-bandwidth number )6)Enable OSPF authentication (ip ospf authentication, or
area authentication)• Set Number of equal routes (maximum-paths number)

Likely Points of CCNA Config Confusion
1)Mechanics of network commands and wildcard masks
2)“Best” options for same 3)OSPF Process ID matching (or not)4)Unique OSPF Router ID
