ndd -set /dev/ip ip_addrs_per_if <number of IFs> You will need to do that on every boot, and thus put it in a script you run either at boot or before starting lots of zones if they don't boot automatically. Reminds me of my old desire to create an SMF service with local 'tunables'. I imagine someone has already done that.
