Connecting to a Routing Matrix

The TX Matrix platform and every T640 routing node 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 platform or T640 routing node Connector Interface Panel (CIP).
  • Management Ethernet—Telnet access via the Fast Ethernet ports on the TX Matrix platform or T640 routing node CIPs.
  • CLI login from one Routing Engine to another—All Routing Engines in the routing matrix are connected to their respective control boards, which in turn are connected to the CIP on the TX Matrix platform (see the TX Matrix Platform 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 ? 
    Possible completions:
  backup               Log in to backup RE
  lcc                  Log in to LCC (0..3)
  master               Log in to master RE
  other-routing-engine  Log in to the other Routing Engine
  re0                  Log in to RE0
  re1                  Log in to RE1

user@router>  request routing-engine login lcc ?
Possible completions:
  <lcc>                Log in to LCC (0..3)

user@router>  request routing-engine login lcc 0 ?
Possible completions:
  backup               Log in to backup RE
  master               Log in to master RE
  re0                  Log in to RE0
  re1                  Log in to RE1

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


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

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.

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