2015 Year-end summary
Updated 20 Jan 2016
The OpenConfig operator group had a busy and productive year in 2015 with progress on several fronts (see some of the highlights below).
We’d like to thank all of the engineers and architects from participating operators who worked hard on all aspects of the effort – building and reviewing models, working with implementors, writing documentation, and getting the word out about the project. And many thanks to all of the engineers, product managers, and account teams at our vendor partners who worked closely with us to help realize the OpenConfig vision of common APIs for network telemetry and automation.
As always, there is lots more to do – we’re looking forward to more progress in 2016.

New models and repository
Updated 18 Oct 2015
The OpenConfig operator group has recently published a number of new models that are currently being reviewed by implementors. These include models for configuration and monitoring of interfaces, VLANs, terminal optics, and RIBs.
OpenConfig model are now available in a new location on our public repository.
Updated BGP and routing policy models
Updated 05 Jun 2015
The OpenConfig operator team has published new versions of our BGP and routing policy models based largely on extensive discussions with a number of implementors. The updated YANG modules are available at the YangModels public repository.
The changes generally do not affect the current structure of the model, but there are a number of fixes that improve clarity, or simplify mappings to implementations.
OpenConfig @ IETF 92
Updated 27 Mar 2015
At this week’s IETF 92 in Dallas, the OpenConfig working group presented several documents and data models:
- Operational Structure and Organization of YANG Models (presented in NETMOD working group)
- Consistent Modeling of Operational State Data in YANG (NETMOD)
- BGP Model for Service Provider Networks (IDR)
- MPLS / TE Model for Service Provider Networks (TEAS, MPLS)
- Routing Policy Configuration Model for Service Provider Networks (RTGWG)
Routing policy model and draft
Updated 19 Feb 2015
OpenConfig published an Internet draft describing policy model for routing. This model provides a generic routing policy framework. The BGP policy model works hooks into the generic model through augmentation. This approach is intended to allow other routing protocol models, VRFs, etc. to add any protocol-specific policy configuration.

Updated BGP and policy models
Updated 06 Jan 2015
Last month, OpenConfig published a new version of the BGP model with a number of changes based on additional operator input as well as from the broader community.
Highlights of the changes:
- Refactored multiprotocol module with explicit set of supported AFI-SAFI combinations (using YANG identities) in a flattened list. Focus was on common config with more AFI-SAFI specific configuration forthcoming.
- Refactored BGP policy module to work with a new general routing policy module (see below) by augmenting it with BGP-specific policy options (conditions and actions).
- Several new configuration items added to base bgp module.
- The bgp-operational module is largely unchanged – the next release is expected to contain a significant update.
- Initial version of a general routing-policy module and associated reusable types module for policy. The routing policy module is currently augmented by the bgp-policy module for bgp-specific routing policy options.
- The IGP policy items in this version of the module are limited to generic items available in widely used protocols like IS-IS and OSPF.
Feedback on the models is welcome and can be posted to the OpenConfig discussion list.
