(not commenting on rs-mark, just the 1:1 VLAN model) Indeed. And the router needs to send out an individual RA per interface. So a router aggregating 20.000 customers will need to send out 20.000 RAs on a regular basis. The 1:1 VLAN model is used a fair amount in DSL deployments, often combined with VLAN stacking to get the necessary scaling. Having each customer on his own interface (no common broadcast domain) is in many ways very nice.
