I don't believe this is real, based on the following test:

deploy a three node setup (controller+network+compute)
setup external net-----router----internal net-----instance
ping from instance to 8.8.8.8

restart l3 agent on network node multiple times - pings don't show a break

Based on the above, this can be marked invalid
