• A.  When the router receives an LSA age is 360s, the LSA is unavailable.
• B.  Both the serial number and the age parameter can judge the LSA is old or new, and the router preferentially compares the sequence parameters, the larger the better.
• C.  If the serial number of the LSA reaches the end value of 0x7FFF, the current router advertises the age is lsa of 3600s.
• D.  When the router receives two LSAs, the serial number is the same, the checksum is the same, and the smaller the age, the better.
