What firmware for my 5406zl

[gregtry]

I need to update my 5406zl switches because I have the firmware revision K.15.05.0002 and it was deleted because of a lot of bugs.

I'm asking yet for what firmware to use : the 2 last posted are K.14.89 and K.15.06.0008. What is the difference between this 2 firmware ?

I've seen another one : K.15.04.0003 which one is certified. Should I use this one ?

Thx

For IPv6support you need K15. Also if you want to be able to use v2 modules. I would install latest version availalbe.

I am using K.15.04.0003 on a mix on 5406zl and 5412zl switches (11 switches total) with no isses.  Performing OSFPv2 for both inter vlan routing and site to site connections.  Using PIM-Sparse as well....
