different link-local addresses, same MAC address. nothing wrong about that try doing "ip a add fe80::1234/64 dev eth0" in your laptop or wherever; voila! you have an extra, manually-set link-local address, that resolves to the same MAC address (when asked by icmpv6) the "uniqueness" of the link-local address you mention, means there should not be two different computers/devices with the same ipv6 address on the same collision domain. It does not mean that a host must have only 1 link-local address. > > why this? bye, bastian > _______________________________________________ > openwrt-devel mailing list > openwrt-devel@lists.openwrt.org > https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel > _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-devel
