Abstract

A network device may receive packets, wherein the network device includes a first routing component, a second routing component, a first forwarding component, a second forwarding component, and a physical interface card concentrator with multiple physical interface cards. The first routing component may provide, to the physical interface card concentrator, a signal indicating that the second forwarding component is to be an active forwarding component. The physical interface card concentrator may cause, based on the signal, a data path for the multiple physical interface cards to be switched from the first forwarding component to the second forwarding component. The first routing component may provide the packets to the second forwarding component. The second forwarding component may provide the packets to the multiple physical interface cards via the data path. The multiple physical interface cards may forward the packets toward destinations associated with the packets.
