The root cause is when deployment finished, we only update router status to active if the status is in pending create. The problem happens when the background sync thread update router status to active, so the status update for vcns_router_binding table is skipped. We fixed this by seperating checking and updating status for router and binding table. Also fixed an issue where Edge is not deleted if neutron service is restarted. The root cause is when neutron service restarts, the cache for router type is empty. And because we delete the router from db before we delete Edge, we're not able to locate the router from db to determine the router type. The fix is to use binding table to determine the router type. Also piggyback a missing attribute for updating Edge interface. It must have been removed by accident when resolving conflict during service plugin merge. Closes-Bug: #1226229 Change-Id: I3d0639d245e71ea2a3faba70fef1a0ebb87e19fd
