Description (partial)

Symptom:
Inconsistency is observed between links in the OSPF topology database and topology of consumer processes like ORR-SPF, BGP-LS and SRTE.

The inconsistency could be in the form of a missing link or a stale link with the topology consumer applications.

Conditions:
This is only in the case of OSPFv2 routing protocol when it is distributing link-state information to consumer process like BGP-LS, SRTE or ORR-SPF when "distribute link-state" command is enabled.
