This shouldn't be a problem, we are using this combination for a couple 
of years. Can you share your complete configuration?

So IPv6 addresses are sent when you remove native_ipv6?

native_ipv6 sets VRRP multicasting protocol to IPv6. I took a short look 
at the code, native_ipv6 and ipv6 virtual ip addresses should not 
interfere with each other.

Not sure how this is implemented. Can you share what the output is from 
wireshark when you turn of native_ipv6?
