As link-local addresses are only valid for a single interface, we can allow to use the same VNI for multiple independent VXLANs, as long as the used interfaces are distinct. This way, VXLANs can always be used as a drop-in replacement for VLANs with greater ID space. This also extends VNI lookup to respect the ifindex when link-local IPv6 addresses are used, so using the same VNI on multiple interfaces can actually work.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
