[j-nsp] EX series junos 12.x version

[Marco Nesler]

hi there,
I need to deploy a small VC with EX4200 switches. For the junos version,
usually i just stick with the JTAC recommended one. In this case NSSU and
non stop bridging are a requirement, so i need to put a 12.something
version on the vc. Any suggestion on a good 12.x release, stable and
suitable for a small production environment ?
The machines will be used basically as a small L2/L3 core, vlan switching,
lacp, inter vlan routing, ospfv2/ospfv3 with single area with around 500
routes.

thanks in advance
