[j-nsp] 2x EX4200 Virtual Chassis Layer2/3 - Which JunOS Version ?

[Giovanni Bellac]

Hello all

I have now spend a lot of time to find out the optimal version of JunOS for our 
newly ordered 2x EX4200s.

1) We will run a 2x EX4200 Virtual Chassis.
2) We will run BGP default routes (NO full table) and announce our /21.
3) We will connect our rack-switches to the Virtual Chassis.

So, we will do Layer2 and some (basic) Layer3.

Should we use the latest service release of 10.0 (= 10.0s11 / 10.0s12) or use 
directly 10.4R2.6 ?

My eyes are on 10.0 and 10.4 because these are longer supported releases.

Thank you in advance.

Regards
Giovanni
