Which OSPFv3 function works differently from OSPFv2?
- metric calculation
- hello mechanism
- OSPF packet types
- election process
Explanation: Both versions of OSPF use the same five basic packet types, the cost metric, and the DR/BDR election process. Hello packets are used in both versions to build adjacencies. OSPFv3, however, uses advanced encryption and authentication features that are provided by IPsec, while OSPFv2 uses either plain text or MD5 authentication.
