Meeting: Thursday, 7th of April, Afternoon session I 14:00-16:00
Still more requests than we could accommodate for in 2h. Reflects good dynamics of the group and enables for prioritization of topics to discuss.
One implementation policy has been setup
Late IPR becoming common
EVPN/DC remains big topic
MVPN continues to be a work item
Yang is maturing
Proposals popping up around automation and OAM
Pretty dense inter-meeting period:
4 new RFCs
- RFC 7716 Global Table Multicast with BGP Multicast VPN (BGP-MVPN) Procedures
- RFC 7734 Support for Shortest Path Bridging MAC Mode over Ethernet VPN (EVPN)

Working Group Status. BFD Wiki
Not meeting in Buenos Aires
- RFC 7726 - Clarifying Procedures for Establishing BFD Sessions for MPLS Label Switched Paths (LSPs)
Multipoint work stable, getting implementations for base spec. Trill has dependency on active head case. Technically ready for WGLC, but no consensus to move forward last IETF-94.
S(eamless)-BFD documents all working their way through the IESG queue.
- We decided to publish the Use Cases draft.
- Documents flagged for language clarification editorial work.
- Various related support drafts in other Working Groups also in IESG:
BFD MPLS MIB stalled.
Crypto:
- Generic keying mehanism stalled.
- SHA-1 similarly stalled.
- New work on optimizing authentication - some progress, needs discussion with security area.
BFD Yang, no progress since last IETF.
- BFD multi-chassis LAG. Logical extension on existing BFD on LAG work.
Meeting on Wednesday
WG Highlights:
- Discussion about adoption of several drafts as WG items
- Discussion about possible move to STANDARDS track
- Things are going generally well (looks like things are on track, ahead of schedule, under budget)
Meeting: Monday - 14:00-15:30 - Afternoon session I
WG Highlights:
- First YANG draft adopted (WSON), 1 individual draft (IP-WDM if), 3 brand new drafts (microwave, WDM management and transport NBI). Coordination with TEAS needed for the latter.

Raw Notes
-
I2RS is a "re-use" protocol where the goal is to re-use and extend
a protocol rather than create new one.
-
This process takes a different path: define the problem,
the new architecture, the potential "re-use" protocols,
the requirements for extension, the security for the protocol
the security environment, and the protocol "strawman"
that describes how the "new protocol" comes from the old protocol.
This mechanism means that we do not "re-invent" the protocols,
and hopefully speed things to market.
-
One challenge/benefit with this process is it takes a great
deal cooperation/flexibility between "old protocol" and "new protocol"
developers.
-
The second challenge is that the process of finalizing
the work requires a lot of "double-checking" to make
sure all the necessary changes.
-
In 2015, we finalized the general scope of
the problem, architecture, two potential "re-use"
protocol (NETCONF/RESTCONF), the extensions,
the security, and the security environment,
a protocol strawman, and our base yang modules.
-
IETF 95 focused on checking to see if we needed
another "re-use protocol", checking to see if the
all the requirements and protocol strawman are
ready to go to netconf or netmod.
-
netmod/restconf chairs/experts + security have been very helpful and cooperative.
-
At the same time, the IETF hackathon had
two projects (NETCONF push) and the I2RS
RIB Yang model project that made significant progress
in getting an open source project up and working.

Meeting Friday/10:00
- YANG models

WG Highlights:
- IPv6 multi-homing with provider-assigned addressing: Work on dest/source routing in RTGWG had been motivated mainly by homenet. RTGWG got a request from v6ops to address the more general case of multi-homing medium-range networks. Discussion ongoing regarding requirements routing based on source prefix for an arbitrary destination prefix vs. only for the default destination prefix.
- RTGWG has several YANG models. Looking for advice for YANG DT regarding impact of opstate and schema mount changes on those models.
- Two WG drafts related to micro-loop avoidance are being implemented. We are incorporating experience from those implementations in the drafts.
WG Status Summary:
-
