Figure: Inside а rоuter, cоntrоl plаne аnd data plane (Module 5)Consider a high-speed router. Each line card of the router holds a copy of the forwarding table. The router has no backup routes. The routing processor of the router crashes, and it takes 30 seconds to restart. The line cards and the switching fabric keep running. The neighbors of the router do not notice the restart. Ten seconds after the crash, one of the output links of the router fails.What happens to the packets that arrive at the router while the routing processor restarts?
