1910 switch, IPv4 routing working, IPv6 routing not working

[ChristophErdle]

Hi,

i have one of the 1910s (JE006A - 1910-24G) at my place and I'm trying to configure IPv6 routing between the locally connected VLANs on this switch. Routing for IPv4 works as expected, but whenever I try to do routing on IPv6 from one of the connected systems traceroute hangs after reaching the switch. The switch itself can ping to the internet through the router in front of it, and also can ping all directly connected endpoints (e.g. a client on the client VLAN, and another switch on the management VLAN).

The data sheet of the switch says it's capable of doing IPv6 routing ( https://www.hpe.com/h20195/v2/getpdf.aspx/4aa1-7808enw.pdf )

Is there anything special to have configured on the 1910 to enable inter-vlan routing and packet forwarding via IPv6? Thanks all for your help, any insight is highly appreciated.

Following is the currently deployed config on the switch:

Do you have static routes on the attached clients?

afaik, default the 1910   (at least its succesor , the 1920)  doesn't send out Router Advertisements.
On 1920, I had to enable them from CLI: 
interface Vlan-interface331
 undo ipv6 nd ra halt

Beware when using these devices as routers.  Their ARP/ND table is very limited.   On IPv6 this even hurts more, since devices have multiples addresses.  (Link Local , Global , Privacy extensions)
