When the last IP address is removed from a netdev, its RIF is deleted. However, if user didn't first remove neighbours and nexthops using this interface, then they would still be present in the device's tables. Therefore, whenever a RIF is deleted, make sure all the neighbours and nexthops (adjacency entries) using it are removed from the relevant tables as well. The action associated with any route using this RIF would be refreshed, most likely to trap. If the kernel decides to remove the route (f.e., because all the nexthops are now DEAD), then an event would be sent, causing the route to be removed from the device.

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.
