Question 376

Which statement about OSPF is false?

Hello packets are used to discover and maintain neighbor relationships. On a broadcast network or an NBMA network, Hello packets can also be used to elect a DR and a BDR.

DD packets describe summary LSDB information by carrying LSA headers.

The intervals at which two routers send Hello packets must be consistent; otherwise, a neighbor relationship cannot be established between them.

DD packets contain headers of all LSAs for periodic LSDB synchronization between OSPF neighbors.
