Currently when programming ECMP routes only one path is programmed in the kernel. There exists an environment variable (KERNELFIB_PROGRAM_ALL_ECMP) that allows users to program all paths from an ECMP route in the kernel. However, setting the variable requires restarting the KernelFib agent. This restart then reprograms all the routes.
