IPv6 Multicast on Procurve 2510-24 switch

[JM_Tetu]

1) sorry for my bad english

2) Wehave some switch HP procurve 2510-24 (J9019A) with 802.1Q (4 vlan).

     2.a one in Q.10 firmware

     2.b others in Q.11.26 or higher

3) IPv6 multicast Router sollication

    3.a) A router sollication  for IPv6 auto-config don't pass with Q.11 (rdisc6 command on linux)

    3.b ) A router sollication  pass with Q.10.

Now, if somebody have an idea :

Where i do my error ? How to do better test ?

if i am alone to have this problem....

Thanks for your help...

PS: A solution is to downgrad in Q10 my HP procurve 2510-24.  But i don't find on HP site how to download this old version....
