ospf6d: Type-7 LSA originated with wrong sequence number
RCA: When Type-7 LSA is updated, the LSDB is searched, if the LSA is present in the LSDB then the LSA is updated with next sequence number and if not then it is originated with the INITIAL sequence number. Here while originating Type-7 LSA Process Level LSDB is searched for instead of area level LSDB. Fix: Search in the area level LSDB and not in the process level. Fixes #9099 Signed-off-by: Mobashshera Rasool <mrasool@vmware.com>
