Known Affected Releases
Symptom: After LC reload, OSPF comes up before ug_merge is completed Conditions: Issue is seen only if below is the sequence of events. 1) Death node notification is received:- 2) IM Delete notification:- 3) First RIB CREATE notification:- 4) Second RIB Create Notification. 5) First RIB merge Notification. 6) IM create callback is received 7) Second RIB merge Notification is received. After step 5, ug_merge is true. Here, IM create notification comes between the first and second ug merge notification. Since we setup ug_merge notification true in step 5 we end up sending UG merge notifcation to clients upon IM create notification.
