OSPF Working Group Highlights from IETF 79 in Beijing

The OSPF Working Group (WG) at IETF 79 in Beijing recently reviewed significant developments in OSPF standards, including RFC 5838, which introduces OSPFv3 support for multiple address families like IPv4 and IPv6. Active drafts were presented on OSPF multi-instance support extending to OSPFv2, and the definition of Transport Instances to separate routing from non-routing information. Other drafts in related working groups were also discussed, including multiple WDM traffic engineering drafts and updates for L3VPN applications. This meeting emphasized ongoing efforts to enhance OSPF functionalities.

  3. Active Drafts • OSPF Multi-Instance supports – Extends multi-instance support on single interface support to OSPFv2 (always in OSPFv3) • OSPF Transport Instance – Defines Transport Instance to advertise “non-routing” information • Separates essential routing information from non-routing information • Support remote neighbors • Sparse Topologies OSPF WG – IETF 79 – Beijing

  4. New Drafts – Not being presented • draft-pillay-esnault-ospf-rbit-00 – Expired draft on extending OSPFv3 R-bit support to OSPFv2. Needs to handle compatibility issues. OSPF WG – IETF 79 – Beijing

  5. Drafts in Other WGs (Not being presented) • CCAMP – Multiple WDM OSPF Traffic engineering drafts • CCAMP – draft-malis-ccamp-rfc5787bis-01.txt – Cleanup of RFC 5787 to bring to standards track and satisfy ITU and OIF requirements • L3VPN – draft-ietf-l3vpn-ospfv3-pece-06 – OSPFv3 equivalent of RFC 4577.
