The Routing Engine constructs and maintains one or more routing tables (see
Figure 4 on page 8). From the routing tables, the Routing Engine derives a table of active
routes, called the forwarding table, which is then copied into the Packet Forwarding
Engine. The design of the ASICs allow the forwarding table in the Packet Forwarding
Engine to be updated without interrupting forwarding performance.
