It won't go to "all members of the VLAN" except for traffic addressed to the all-hosts address. Link-local traffic has similar multicast and unicasting capabilities to any other IPv6 address. All multicast traffic can leak to uninterested receivers, including link-local multicast. This includes, for example, the solicited-node addresses used by Neighbor Discovery. Unicast link-local traffic won't be "leaked" because there will be an L3 destination to L2 destination mapping. This is not different than IPv4. -- Jeff S Wheeler <[email protected]> Sr Network Operator / Innovative Network Concepts _______________________________________________ nvo3 mailing list [email protected] https://www.ietf.org/mailman/listinfo/nvo3
