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

[Bill Blackford]

I'm running a 2x EX4200 VC on 10.0R4.7. I haven't found any issues. Each rack switch connects up on LAG bundles. No BGP, this V-chassis acts as a small data center build.

I have other EX4200's on 10.0S1.1 doing OSPF and BGP and they're performing well. So far, I haven't seen the need to upgrade to S11 or S12 but probably will at my next reasonable maintenance window.

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
