ospfLsdbChecksum
Module: BTI-7000-MIB
OID (symbolic): BTI-7000-MIB::ospfLsdbChecksum
OID (numeric): 1.3.6.1.4.1.18070.2.2.1.13.4.1.7
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 ospfLsdbChecksum?
Provides the checksum of an LSA's contents (excluding the age field) stored in the OSPF link state database, used to verify the integrity of the advertisement. Because the age field is excluded, routers can increment age without recalculating the checksum.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18070.2.2.1.13.4.1.7 snmpwalk -v2c -c public <target> BTI-7000-MIB::ospfLsdbChecksum
Get a specific instance (index 1):
