Well, I don't know specifically about IPv6, but in general, connectivity
between a router and nexus using vPC is not recommended, but the result is
also very platform specific.
The preferred way if I remember correctly is to have 2 separate l3 links
and use eg OSPF instead of etherchannel for load balancing & redundancy.

.
Maybe IPv6 is a bit more problematic than IPv4 because of the use of
multicast.

Kind regards,
