Illustrates how, with the Packet I/O functionality, you can use Linux applications to manage communication with the IOS XR interfaces. It describes how the OS environment must be set up to establish packet I/O communication with hosted applications.
Application hosting environments
Explains how application hosting environments allow Linux applications to manage communication with IOS XR interfaces using Packet I/O functionality.
Verify reachability of IOS XR and Packet I/O infrastructure
Use this task to verify that interfaces configured on IOS XR are programmed into the Linux kernel and that the packet I/O infrastructure provides default reachability for off-the-shelf Linux applications.
Programme routes in the kernel
Programme basic routes into the Linux kernel to allow applications to send or receive traffic using the IOS XR network stack.
Linux-managed IOS XR interfaces
This concept explains how Packet I/O enables IOS XR interfaces to be managed directly by Linux, allowing standard automation tools to configure and control interfaces.
