Connecting to a Routing Matrix with a TX Matrix Router

 

The TX Matrix router and every T640 router can each be configured with two Routing Engines to provide redundancy and graceful Routing Engine switchover capabilities. You can connect to each Routing Engine in the following ways:

  • Console/AUX—Asynchronous access via the console and auxiliary ports on the TX Matrix router or T640 router Connector Interface Panel (CIP).

  • Management Ethernet—Telnet access via the Fast Ethernet ports on the TX Matrix router or T640 router CIPs.

  • CLI login from one Routing Engine to another—All Routing Engines in the routing matrix with a TX Matrix router are connected to their respective control boards, which in turn are connected to the CIP on the TX Matrix router (see the TX Matrix Router Hardware Guide for more details). After you log in to one Routing Engine, you can connect to another Routing Engine as follows:

    user@router> request routing-engine login ?
    Note

    Because the routing matrix appears as a single router, we recommend that you access the master Routing Engine of the TX Matrix router to perform all configuration tasks for the routing matrix. Under normal operating conditions, you do not need to access or configure the T640 router directly. If you access a Routing Engine on a T640 router, the following warning is displayed:

    user@router> request routing-engine login lcc 0 re0

To manage the backup Routing Engines on all components (for example, to upgrade Junos OS), log in to the TX Matrix router backup Routing Engine and perform the necessary operations.
