• Both OSPFv2 and OSPFv3 use the router configuration network command to advertise networks.
• Both OSPFv2 and OSPFv3 use multicast destination addresses for link-state packets.
• OSPFv2 uses a 32 bit router ID and OSPFv3 uses a 128 bit router ID.

Both OSPFv2 and OSPFv3 use a 32 bit router ID. Both OSPFv2 and OSPFv3 require the DR/BDR election to occur on multiaccess networks.
