A) When the router receives two LSAs, where the sequence number is the same and the checksum is the same, the smaller the age, the better
B) When the router receives-The age of the LSA is set to 3600S, the LSA is unavailable
C) Both the serial number and age parameters can determine whether the LSA is old or new, and the router prioritizes the sequence to participate in the teaching, and the larger the better
D) If the serial number of the LSA reaches the end value of Ox7FFFFFFF, the current router advertises an LSA with an age of 3600S
