# have you enabled IPv6 on the interface at all? if the bridge device is br_a_1, then do this:
# sysctl net.ipv6.conf.br_a_1.disable_ipv6=0
# sysctl net.ipv6.conf.br_a_1.autoconf=1
# sysctl net.ipv6.conf.br_a_1.accept_ra=1
# sysctl net.ipv6.conf.br_a_1.accept_ra_defrtr=1
# less /proc/sys/net/ipv6/conf/br_a_1/disable_ipv6
# Every IPv6 address, even link-local ones, automatically subscribe to a multicast group based on its last 24 bits. If multicast snooping is enabled, the bridge filters out (almost) all multicast traffic by default. When an IPv6 address is assigned to an interface, the system must inform the network that this interface is interested in that particular multicast group and must be excluded by the filter. The following is a good introductory video: https://www.youtube.com/watch?v=O1JMdjnn0ao
# Multicast snooping is there to prevent flooding the network with multicast packets that most systems aren't interested. You can disable multicast snooping in small deployments without noticing any big difference. But this may have significant performance impact on larger deployments. You can disable snooping with:
# echo -n 0 > /sys/class/net/br_a_1/bridge/multicast_snooping
# echo -n 0 > /sys/class/net/br_a_2/bridge/multicast_snooping
# echo -n 0 > /sys/class/net/br_a_3/bridge/multicast_snooping
# echo -n 0 > /sys/class/net/br_a_4/bridge/multicast_snooping
# echo -n 0 > /sys/class/net/br_a_5/bridge/multicast_snooping
# If you want to protect your VMs from unwanted traffic and unnecessary packet processing, you can leave snooping enabled but also enable a multicast Querier on the network. A Querier will periodically broadcast query packets and update snooping filters on switches and bridges. It is possible to enable a Querier on your system with:
# echo -n 1 > /sys/class/net/br_a_1/bridge/multicast_querier
# echo -n 1 > /sys/class/net/br_a_2/bridge/multicast_querier
# echo -n 1 > /sys/class/net/br_a_3/bridge/multicast_querier
# echo -n 1 > /sys/class/net/br_a_4/bridge/multicast_querier
# echo -n 1 > /sys/class/net/br_a_5/bridge/multicast_querier
