On a broadcast network, both the DR (Designated Router) and BDR (Backup Designated Router) use...

Comprehensive and Detailed Explanation:

In OSPF, routers on a broadcast network elect a DR and BDR to reduce overhead.

The multicast address 224.0.0.6 is used exclusively by the DR and BDR to receive LSU packets.

Other routers send LSU packets to 224.0.0.6, and the DR forwards them to 224.0.0.5 (all OSPF routers).
