Title:
L3: agent may do double work upon start/resync
Status in neutron:
Won't Fix
Bug description:
The issue was noticed during scale testing of DVR.
When l3 agent starts up it initiates a full sync with neutron server:
requests full info about all the routers scheduled to it. At the same time
agent may receive different notifications (router_added/updated/deleted) which
were sent while agent was offline or starting up. For each of such
notifications the agent will request router info again, so server will have to
process it twice (first is for resync request).
The following optimization makes sense: when agent is about to
fullsync we can skip all router notifications since fyllsync should
bring the agent up to date anyway.
