One stack connected to the OSA can be designated as the primary_router. It doesn't matter if they are in seperate LPARS or guests in the same LPAR, only one, regardless of microcode level. If you need to have two stacks with primary_router specified, you need to OSA cards. Note that unless z/OS is actually acting as a virtual router, there's no need for it to specify primary_router.
