A routing matrix is a multichassis architecture that consists of a TX Matrix platform and from one to four T640 routing nodes. From the perspective of the user interface, the routing matrix appears as a single router. The TX Matrix platform controls all the T640 routing nodes in the routing matrix, as shown in Figure 10.
Figure 10: Routing Matrix
You configure and manage the TX Matrix platform and its T640 routing nodes in the routing matrix through the CLI on the TX Matrix platform. This means that the configuration file on the TX Matrix platform is used for the entire routing matrix.
Because all configuration, troubleshooting, and monitoring is performed through the TX Matrix platform, we do not recommend accessing its T640 routing nodes directly (through the console port or management Ethernet [fxp0]). If you do, the following messages appear when you first start the CLI through a T640 routing node:
- % cli
- warning: This chassis is a Line Card Chassis (LCC) in a
multichassis system.
- warning: Use of interactive commands should be limited
to debugging.
- warning: Normal CLI access is provided by the Switch Card
Chassis (SCC).
- warning: Use 'request routing-engine login scc' to log
into the SCC.
- {master}
These messages appear because any configuration you commit on a T640 routing node is not propagated to the TX Matrix platform or other T640 routing nodes. For details, see Committing Configurations.
