  1. draft-ietf-v6ops-ipv6-cpe-router-bis-01 IETF 81, Quebec City July 24-July 29, 2011 v6ops Working Group Hemant Singh (shemant@cisco.com) Wes Beebee (wbeebee@cisco.com) Chris Donley (CableLabs) Barbara Stark (AT&T) Ole Troan, Editor (ot@cisco.com) and many other folks from Cable, DSL, Cellular, & Zigbee standards Advanced Requirements for IPv6 Customer Edge Routers

  2. Background • Design team consisting of operators, BBF, Cablelabs and IETF participants • cpe-router@external.cisco.com • RFC6204 “Basic IPv6 CE…” • Successful! • 6204 strategy: • Punt on anything we don’t know how to do, contentious or hard • “Advanced IPv6 CE” scope: • “Whatever low hanging fruits left”

  3. Updates in the -01 version • Removed requirement for ND proxy • Clarified text in the DNS section and removed most text with MAY requirements. • Added a new DHCPv6 requirement – see section 5.7. • When the WAN interface sends a DHCPV6 SOLICIT message, the CE router SHOULD request all mandatory information (such as IA_NA and IA_PD options) in the SOLICIT regardless of whether any partial information was received in response to previous SOLICITs. • Added new and modified text for 6rd support. • Clarify support for user configurable, DHCP option 212 support • 6rd hub and spoke mode requirement

  4. Homenet split • LAN side requirements to homenet • D-1 (DNS), LMMLD-{1, 2} (MLD), LM-1 (MLD) • R-1 (Hierarchical PD), Q-1 (QOS) • WAN side requirements in v6ops • WMLD-1 (MLD) • DLW-{1,2,3,4,5} (DS-lite) • 6RD-{1,2,3,4} (6RD) • Q-1 (QOS) • Transition technology co-existence

  5. Questions • Split the LAN side requirements off to the homenet WG? • What to do with remaining requirements? • Abandon? • Move to softwires as a “transition mechanism interoperate” draft? • RFC6404: resubmit RFC6204 with the 6rd and DS-lite requirements? • Continue?
