Which of the following statements are true about the OSPF neighbor status? (Choose all that apply.)
The master/slave relationship of OSPF is indeed formed in the ExStart state, making option A correct. After LSDB synchronization is completed, the router state does change to Full, supporting option B. The sequence number of DD packets is determined in the Exchange state, confirming option C. Lastly, in the Exchange state, routers send DD packets that briefly describe link state information to each other to describe the content of the local link state database (LSDB), hence option D is also correct.
A,B.C.D
BD correct
