If the device for a nexthop in a multipath route is deleted, the nexthop is effectively removed from the route. Currently, a route dump still returns the nexhop though without the device set: $ ip -f mpls ro ls 100 nexthopvia inet 10.11.1.2 dev br0 nexthopvia inet 10.100.3.1 dev eth3 $ ip li del br0 $ ip -f mpls ro ls 100 nexthopvia inet 10.11.1.2 dev * dead linkdown nexthopvia inet 10.100.3.1 dev eth3 Since the nexthop is effectively deleted, drop the hop from the route dump.

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.
