Description: This field is the checksum of the complete contents of the advertisement, excepting the age field. The age field is excepted so that an advertisement's age can be incremented without updating the checksum. The checksum used is the same that is used for ISO connectionless datagrams; it is commonly referred to as the Fletcher checksum.
What is prvtOspfExtLsdbChecksum?
This is the Fletcher checksum covering this external LSA's contents except the age field, the external-LSDB counterpart of prvtOspfLsdbChecksum, useful for confirming two routers hold an identical copy of the same external route advertisement.
