Packet Forwarding Engine—Performs Layer 2 and Layer 3 packet switching, route
lookups, and packet forwarding.
Routing Engine—Provides Layer 3 routing services and network management.
The Packet Forwarding Engine and the Routing Engine perform independently but
communicate constantly through a 100-Mbps internal link. This arrangement provides
streamlined forwarding and routing control and the ability to run Internet-scale networks
at high speeds. Figure 34 on page 59 illustrates the relationship between the Packet
Forwarding Engine and the Routing Engine.
