This table defines secondary interfaces for each virtual router. A virtual router may have multiple interfaces. A virtual router interface is uniquely identified by its {cadVrInterfaceSubifIndex, cadBgIndex} tuple. Each virtual router interface may also have zero(0) or one(1) primary IP addresses associated with it. There must be a primary address bound to an interface before any secondary IP addresses may be assigned to that same interface. There may be as many secondary IP addresses as desired.
