No it is not. It is a limit to reduce memory pressure. > Example: rdomain 50, vport50, veb50.

Would there > be any appetite to grow the rdomain limit to at least a 16bit field? This is a dumb reason that wastes memory. When creating rdomain 50 the system will allocate 48 unused slots. Which may be ok but then someone comes up with rdomain 4000 for vlan4000. There may be a need for an extra lookup indirection but implementing is not trivial. -- :wq Claudio
