The Routing Engine constructs and maintains one or more routing tables (see Figure 18
on page 35). 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.
