Initially INP LSA is originated, when connected interface comes up. As neighbor is not up, LSA is not transmitted but stored in DB. As NSM transition to FULL, INP is scheduled but ospf6_flood() would not originate the LSA as current DB and new INP LSA same so it discards the new LSA. When Neighor becomes FULL, originate INP via flushing current DB copy and generate new. This is introduced as PR 1738 introduce, premature aging of LSAs in nbr table as R1 going down. upon neigbor coming up, INP was not updated to new age. Ticket:CM-19926,CM-19945 Testing Done: Topology R3 --- R1 -- R2, R1 have INP LSA. After frr restart R2 and R3 re learnt R1's INP LSA as new neighbor(s) come up.
