swL3OspfExternalLsdbChecksum
Module: DGS3000-10TC-L3MGMT-MIB
OID (symbolic): DGS3000-10TC-L3MGMT-MIB::swL3OspfExternalLsdbChecksum
OID (numeric): 1.3.6.1.4.1.171.11.133.1.1.3.13.2.1.8
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This field is the checksum of the complete contents of the advertisement, except the age field. The age field is the exception 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 swL3OspfExternalLsdbChecksum?
The Fletcher checksum over this external LSA's contents, excluding the age field so the checksum doesn't need updating merely because the LSA aged. Admins can compare checksums across routers to confirm they hold identical copies of the same external route advertisement.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.11.133.1.1.3.13.2.1.8 snmpwalk -v2c -c public <target> DGS3000-10TC-L3MGMT-MIB::swL3OspfExternalLsdbChecksum
