L3 routing is done by the network node. L3 is already blocked by security groups. The vlans provide L2 isolation. Essentially we handle this with convention, as in tell your tenants not to open up their firewalls if they don't want to be accessed by other tenants.<div><br></div><div>for example:</div><div><br></div><div>nova secgroup-add-rule default tcp 22 22 192.168.0.0/24 # or some other restricted range</div><div><br></div><div>instead of:</div><div><br></div><div>nova secgroup-add-rule default tcp 22 22 0.0.0.0/0</div><div><br></div><div>People seem to expect l3 traffic to be totally blocked between tenants. I'm not totally convinced that is good behavior, but it should be possible to produce a patch that will do this.
