多选题Which three statements about the EIGRP routing protocol are true?（）AEIGRP supports five generic packet types, including hello, database description (DBD), link state request (LSR), link - state update (LSU), and LSAck.BEIGRP sends periodic hello packets to the multicast IP address 224.0.0.10.CEIGRP will not form a neighbor relationship with another peer when their K values are mismatched.DEIGRP sends periodic hello packets to the multicast IP address 224.0.0.9.EE IGRP will form a neighbor relationship with another peer even when their K values are mismatched.FEIGRP supports five generic packet types, including hello, update, query, reply, and ACK packets.
