Abstract
Examples disclosed herein relate to a method comprising detecting, by a bi-directional forwarding detection (BFD) protocol, a link failure of a link associated with a network device on a network. The method may include notifying, by the BFD protocol, a routing protocol and a hardware plugin about the link failure and identifying, by the routing protocol, an updated route for the network that does not include the network device. The method may also include deleting, by the hardware plugin, any routes programmed into a forwarding information base (FIB) including the first network device upon receiving the notification from the BFD protocol and installing, by the hardware plugin, the updated route into the FIB to be used for forwarding network traffic on the network.
