This library contains a Go implementation which can parse an IS-IS LSP and output it as gNMI Notifications containing OpenConfig encoded data.
Two public APIs are provided:
-
ISISBytesToLSP([]byte, int): takes an input byte array containing an IS-IS PDU beginning at the LSP ID field, and returns a ygot.ValidatedGoStruct containing the parsed LSP as per the OpenConfig schema, a bool indicating whether the LSP was succesfully parsed, and an error. -
RenderNotifications(*oc.Lsp, ISISRenderArgs): takes an input GoStruct corresponding to an IS-IS LSP, and returns a slice of gNMI notifications which correspond to the contents of the LSP, which can be used in streaming telemetry implementations.
The generated code for the OpenConfig library uses a subset of the schema to improve the efficiency for IS-IS LSP parsing operations.
This is not an official Google product.
