Would you mind making some dumps for ~10 minutes with tcpdump on all bridge ports and the bridge interface itself with a filter "icmp6" and uploading the result somewhere? Also provide a dump from "bridge mdb show dev $bridge" please (if possible - not sure whether that's available on the ancient 2.6.32 kernel as used on RHEL6u6). Cheers, Linus
