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 connec- tionless datagrams; it is commonly referred to as the Fletcher checksum.
What is nsVrOspfExtLsdbChecksum?
The Fletcher checksum of this external LSA's contents (excluding the age field), used internally to detect corrupted or tampered advertisements during flooding.
