Hi, If I understand RFC 4291 correctly, the ipv6 multicast ip-addresses ffx1:<scope> are "interface local scope. According draft-ietf-ipngwg-scoping-arch-02 "The interface-local scope spans a single interface only; a multicast address of interface-local scope is useful only for loopback delivery of multicasts within a single node, for example, as a form of inter-process communication within a computer". This is exactly what I want to do, however when I try it and make a small C-program that spits out UDP packats to the ipv6 multicast address ff11::1234, I do see them show up on remote machines on my LAN. So it looks like these packets do leave my local compute which is -I think- not what the RFC tells me. Or am I missing something? The machine on which I have tested this runs ubuntu 10.04.1 LTE with kernel 2.6.32-30-generic Anybody any ideas? links: - RFC4291: http://tools.ietf.org/html/rfc4291#section-2.7 - draft-ietf-ipngwg-scoping-arch-02: http://tools.ietf.org/html/draft-ietf-ipngwg-scoping-arch-02) Cheerio!
