  1. Link Scoped IPv6 Multicast Addresses draft-ietf-ipv6-link-scoped-mcast-01.txt Jung-Soo Park, Myung-Ki Shin ETRI 54th IETF – Yokohama, Japan

  2. History • IETF52, December 2001 • Individual draft was presented • <draft-park-host-based-mcast-00.txt> • IETF53, March 2002 • Accepted as a working group document • covers link-local scope • Title was changed according to Bob’s comment • <draft-ietf-ipv6-link-scoped-mcast-00.txt> • IETF54, July 2002 • Revised version(01) was published (editorial changes) • <draft-ietf-ipv6-link-scoped-mcast-01.txt>

  3. Link Scoped Multicast Addresses • flgs field should use the same flags defined in unicast prefix-based method • interface ID field is derived from unicast address 4-bit 4-bit 16-bit 32-bit 8-bit 64-bit 11111111 flgs scop reserved Interface ID group ID

  4. Multicast Scope • Our draft scope • Covers link-local scope • scope <= 2 cf) Unicast prefix-based multicast • <draft-ietf-ipngwg-uni-based-mcast-03.txt> • Does not cover link-local scope • scope > 2

  5. Next Steps • Ready for wg last call • Proposed standard • Cf., “Unicast prefix based multicast addresses” has been already approved by IESG (now, RFC editor queue) • Implementations • We’re implementing in Linux 2.4.18 • First code will be available on October or so
