この場所には #dnstudy で発表した資料「#dnstudy 01 顿狈厂再入门」を置いていましたが、DNS Summer Days 2013およびDNS Summer Days 2014 チュートリアル用に資料を大幅に修正?加筆したため、新しい資料をアップロードし直しています。
This document defines functions for registering a Quagga routing daemon module with a gRPC server and handling configuration changes. It registers the "quaggad" module and a show command via gRPC. It also defines a function to subscribe to configuration changes and send updates to a gRPC stream. When a change is received, the quaggaConfig function validates and applies the change or synchronizes state.
The YANG syntax is similar to C and C++ and uses a C-like syntax that was chosen for its readability. This section introduces the YANG syntax. While SMIv1, SMIv2, and SPPI are bound to specific protocols like SNMP and COPS-PR, the purpose of SMIng is to define a common data definition language that can specify data models independently of protocols.
