I2RS is finalizing initial data modules

*[Service and L1 will finalize after this group]

Open Issues for drafts: *RIB should be aligned with routing-configuration *FB-RIB is feature for config and ephemeral, but

there is no config. Will define

  • Topology models are considering a "write"
  • that creates pieces of topology.
  • Debate will continue on list.

I2RS protocol proposal

  • Initial proposal for RESTCONF

I2RS WG next steps

  • finish Data Models
  • Accept Protocol Data Models in order to guide data models before going to WGs,

Agenda Charter Minutes



  • L2TPExt is not meeting in Yokohama-shi


  • Meeting: Tuesday, November 3, 15:20, Room 301
  • WG Highlights:
    • LISP Impact approved by IESG but revised document needed.
    • IANA allocated prefix 2001:5::/32 as requested by LISP EID Block document.

  • WG Status Summary:
    • No new RFCs
    • LISP DDT revised document needed (fixing comment from document shepherd)
    • The WG group is rechartering
      • Proposed Work Items:
        • NAT-Traversal
        • Mobility
        • Data-Plane Encryption
        • Multicast: Support for overlay multicast by means of replication as well as interfacing with existing underlay multicast support.
        • Data models for management of LISP.
        • Multi-protocol support: Specifying the required extensions to support multi-protocol encapsulation (e.g., L2 or NSH – Network Service Headers). Rather than developing new encapsulations the work will aim at using existing well-established encapsulations or emerging from other Working Grops such as NVO3 and SFC.
        • Alternative Mapping System Design. By extenting LISP with new protocols support it is also necessary to develop the required mapping function extensions to operate LISP map-assisted networks (which might include Hierarchical Pull, Publish-Subscribe, or Push models and related security extension).
