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 ?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 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--- JUNOS 7.0-20040625.1 built 2004-06-25 19:51:38 UTC % % 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.
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.
