Which two parameters are minimally required on an active interface for OSPFv2 to operate? (Choose two.)

For OSPFv2 to operate on an interface, it minimally requires an OSPF process ID and an OSPF area. The OSPF process ID is a locally significant number that identifies the OSPF routing process on the router. The OSPF area defines the logical grouping of routers and interfaces within the OSPF domain. Without both of these parameters, the interface cannot participate in OSPF routing. OSPF MD5 authentication key is optional for securing OSPF updates, not a minimum requirement for operation. IPv6 addresses are used for OSPFv3, not OSPFv2, which operates on IPv4. The OSPF stub flag is an optional configuration for specific area types, not a basic operational requirement.
