i've just installing CNR 126.96.36.199
previously i was using CNR 5.5.9 and ubr7246. each ubr is handled by one CNR, and in ubr7246 there was only one management interface, so i can easily map client default to management scope.
now there are more than one uBR that my new CNR should handle. is it true that my workaraund is to configuring multiple primary scope in my new CNR? or maybe there are better solutions.
