Cisco IOS XR 6.0 and YANG
IOS XR has featured a NETCONF interface for quite some time but it was only with the 5.3.0 release that Cisco coupled it with proper YANG modeled configuration and operational data. Before that they used XML Schema Definition (XSD) to describe the data transported over the XML agent / NETCONF interface.
To be honest the difference between what Cisco calls XML agent and their NETCONF server is still a bit unclear to me. Maybe I'll dig through that sometime but I'm all focused on NETCONF/YANG and we know Cisco is headed in that direction so looking at the XML agent would be merely to satisfy my curiosity.
Unlike JUNOS, which features one massive YANG model (it's over 250k lines), Cisco has opted to split the configuration into many smaller YANG models. When YANG models were introduced in 5.3.0 they shipped it with 61 models, totalling 12451 lines. Naturally the number of models or lines in those models doesn't give an exact figure on coverage of configurational or operational data but I hope it gives a hint at least. The coverage of these 61 models was actually rather poor so in practice it wasn't usable for anything.
5.3.1 bumped the number to 24812 lines over 99 models. Obviously an improvement but still pretty far from usable. For example, neither 5.3.0 or 5.3.1 featured any configuration of routing protocols. You could configure interfaces, IP addresses, some system settings and so forth but far from being usable to configure an entire router.
5.3.2 brought along BGP, policy configuration, some file system stuff as well as a number of updates. The number of models only increased from 99 to 106 but lines went from 24812 to 45775 of which the lions share are from the BGP models and in particular the BGP operational model. Progress after all!
There is a YangModels repository on GitHub, where you can conveniently browse the models available in XR up to 5.3.2.
I work with the TeraStream project within Deutsche Telekom and we have been an early adopter of NETCONF and YANG. In fact, it's one of the foundational pillars of the network architecture. Everything MUST (RFC2119) support NETCONF/YANG. We have worked with Cisco for years and have private builds of XR featuring loads of YANG models (142575 lines spread over 242 models). As I spend a lot of time with NETCONF & YANG in my every day work, a lot of people ask me about the state of the implementations and how they can use it. The conversations usually go down with me saying something like "NETCONF/YANG works great on XR… bla bla … as long as you have a private build with all YANG models". Unlike TeraStream, which is in some form of pilot state, most people run actual production networks and just want working solutions. Running a private test build isn't for them.
Cisco released XR 6.0 yesterday and I downloaded a demo of XRv today to have a look at the coverage of YANG models. Have a look at this (and sorry for the long output):

Would you look at that! 184 models. I haven't fetched the models from the box just yet but I recognize a few from our private build, like clns-isis for IS-IS config. At the end of the output you can see that Cisco has included a few OpenConfig models as well! They have previously announced this, both privately and publically but it's always nice to see it actually happen, especially as I am involved in the OpenConfig working group, representing the interests of DT/TeraStream.
I'll be trying this out and comparing it to our private builds but I think it's safe to say that Cisco has finally included enough YANG models to make it possible to use NETCONF & YANG as the primary interface to configure and operate your XR box!
