Example: Routing Matrix Configuration

Figure 15: Routing Matrix Topology Diagram

Figure 15 shows Routing Matrix A, a basic routing matrix consisting of a TX Matrix platform and two T640 routing nodes. The TX Matrix platform is named SCC and the nodes are named LCC0 and LCC2. The routing matrix is acting as a provider edge (PE) router in a Layer 2 circuit network. SONET interface so-1/1/0 in node LCC0 connects to an IP/MPLS core network, and Asynchronous Transfer Mode 2 (ATM2) intelligent queuing (IQ) interface at-17/1/0 in node LCC2 runs Layer 2 circuit trunk mode to connect to an ATM switch. (For more information about Layer 2 circuit trunk mode, see Option: Configuring Layer 2 Circuit Trunk Mode on ATM2 IQ Interfaces or the JUNOS VPNs Configuration Guide.)

Some key considerations for this configuration are as follows:

• Treat the routing matrix like a single routing platform and execute all configuration and operational commands on the TX Matrix platform SCC.
• Create configuration groups for each Routing Engine in the routing matrix by using groups re0, re1, lcc0-re0, lcc2-re0, lcc0-re1, and lcc2-re1. In the groups, configure hostnames, default routes, and management interfaces.
• To configure interfaces, use the routing matrix FPC numbering convention of slots 0 through 31.
• To enable ATM2 IQ trunk mode and other chassis-based commands, include the lcc lcc-number statement at the [edit chassis] hierarchy level and use the hardware FPC slot numbers 0 through 7 of node LCC2.
• Configure most other processes as usual, such as routing, class of service (CoS), and firewalls.
