The routing table is not available on the standby supervisor in EOS, hence running any diagnostics or scripts that talk to the standby supervisor through the forwarding plane is not possible. This feature adds a new Cli command that configures a default route on a standby supervisor. This default route will offload routing to the forwarding plane. Therefore it behaves the same way as the routing table on the active supervisor. The default route is installed on all VRFs.

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.
