I do not really understand why you set up a bridge twice but I use a 
rather similar setup for an Online.net hosted server with a dual stack 
IPv4+IPv6.

As an example, my interfaces file is like this (Xen aware):

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto xenbr0
iface xenbr0 inet static
	bridge_ports noregex eth0 regex vif.*
	address
	netmask 255.255.255.0
	network
	broadcast
	gateway
	bridge_maxwait 5
	bridge_stp off
	bridge_fd 0

iface xenbr0 inet6 static
	address 2001:bc8:
	netmask 56
	accept_ra 2
	pre-up sleep 10 # see bug #783387
	pre-up dhclient -cf /etc/dhcp/dhclient6.conf -pf 
/run/dhclient6.xenbr0.pid -6 -P xenbr0
	pre-down dhclient -x -pf /run/dhclient6.xenbr0.pid

Hope this helps.
