Building a Custom Kernel Branch
Custom kernel branches make use of a .bbappend file to add the feature to the linux-yocto kernel.
Incremental Kernel Changes with Git
Git options facilitate incremental kernel changes in a distributed development environment.
Creating a CGL Platform Project
The first step towards creating a CGL platform project is to configure it to match your end-platform system requirements.
CGL Platform Project Layers
The platform project configuration files necessary for Carrier Grade Linux (CGL) features include additional layers and the wrlinux-cgl disto as described in this section.
Customizing the CGL Platform Project
Once your platform project is created and your development environment is ready, you can make configuration changes to define your platform project features.
Virtual Routing and Forwarding Overview
In IP-based computer networks, virtual routing and forwarding (VRF) is a technology that allows multiple instances of a routing table to co-exist within the same router at the same time.
Components of a VRF Build
To use VRF and understand what supports its functionality, refer to the VRF-related files in the root file system, located in the build directory tmp-glibc/work/core2-64-wrs-linux/vrf/1.1-r0/wrlinux-vrf sub-directory.
