[CentOS] IPv6 routing with 2 different prefixes

Hello

I've got two prefixes, one /48 and one /64

let's say these two
2001:db8:0815::/48
2001:db8:4711:cafe::/64

the router has on it's ethernet interface the following to IPv6 addresses:
2001:db8:0815::1/48
2001:db8:4711:cafe::1/64

a windows box has
2001:db8:0815::17/48
and
2001:db8:0815::1
as it's gateway

a linux box has
2001:db8:4711:cafe::11/64
and
2001:db8:4711:cafe::1
as it's gateway

why can only the router do
ping6 2001:db8:0815::17
and not the linux box?

is there a missing IPv6 route?

Thanks,
Walter
