Figure 3: Routing Matrix Routing Engine Connections

The TX Matrix Routing Engine connects to a high-speed switch through a 1-Gbps link
within the host subsystem. The switch provides a 100-Mbps link to each T640 Routing
Engine. The 100-Mbps links are provided through the UTP Category 5 Ethernet cable
connections between the TX-CIPs and the T-CBs in the T640 routers.
The kernel synchronization process running on each T640 router Routing Engine
synchronizes the TX Matrix Routing Engine's forwarding table with the forwarding table
on a T640 router. The Junos kernel running on each T640 router Routing Engine copies
its forwarding table to all Packet Forwarding Engines in each T640 router.
Figure 4 on page 10 illustrates the control plane architecture.
