[j-nsp] Ethernet switching/bridging on SRX High-End

[Stefan Fouant]

Hi,

Actually, you can absolutely do transparent mode on High End SRX Platforms by way of bridge-domains... And if I recall correctly in 11.1 and higher this is also the same way you configure transparent mode on the branch devices as well (i.e. no ethernet-switching family).
