[rbridge] Configuration of VLANs vs selfconfiguration

[Guillermo Ibáñez]

   IMHO, with this restrictive interpretation of zero configuration we 
solve only half of the configuration problem.    
   Anyway, if this is the prevalent opinion, I suggest to add  this 
clarification  to the draft (zero configuration for single LAN, equal 
configuration for VLANs as standard bridges).
