prvtOspfLsdbChecksum
Module: PRVT-OSPF-MIB
OID (symbolic): PRVT-OSPF-MIB::prvtOspfLsdbChecksum
OID (numeric): 1.3.6.1.4.1.738.1.6.4.2.1.14.1.7
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
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 prvtOspfLsdbChecksum?
This is the Fletcher checksum covering the entire LSA contents except the age field (which is excluded so age can tick upward without invalidating the checksum). Comparing this value across routers is a quick way to confirm they hold identical copies of the same LSA.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.738.1.6.4.2.1.14.1.7 snmpwalk -v2c -c public <target> PRVT-OSPF-MIB::prvtOspfLsdbChecksum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.738.1.6.4.2.1.14.1.7.1 snmpget -v2c -c public <target> PRVT-OSPF-MIB::prvtOspfLsdbChecksum.1
