Figure 31: Routing Matrix Routing Engine Connections

The TX Matrix Plus Routing Engine connects to a high-speed switch through a 10-Gbps

link within the host subsystem. The switch provides a 1-Gbps link to each T1600 Routing

Engine. The 1-Gbps links are provided through the UTP Category 5 Ethernet cable

connections between the TXP-CBs and the LCC-CBs in the T1600 routers. (For more

information about connecting TXP-CBs to LCC-CBs, see "Control Plane Connections

from the TX Matrix Plus Router to the T1600 Routers" on page 58.)

The kernel synchronization process running on each T1600 Routing Engine synchronizes

the forwarding table on the TX Matrix Plus Routing Engine with the forwarding table on

the T1600 router. The Junos kernel running on each T1600 Routing Engine copies its

forwarding table to all Packet Forwarding Engines in the T1600 router.

Figure 32 on page 58 illustrates the control plane architecture.
