Configuring Specific LCC Chassis Features for the T640 Router

The kernel synchronization process runs on each T640 router's Routing Engine (see
Figure 75 on page 151). This process synchronizes the TX Matrix Routing Engine's forwarding
table with the forwarding table on a T640 router. The Junos kernel running on each T640
router's Routing Engine copies its forwarding table to all Packet Forwarding Engines in
the router.
The Routing Engine kernel provides the underlying infrastructure for all Junos OS
processes. The Routing Engines in the T640 routers run their own kernel, which is
synchronized with the kernel running on the TX Matrix Routing Engine (see "Kernel
Synchronization Process" on page 154).
The kernel running on the TX Matrix Routing Engine maintains the master forwarding
table for the routing matrix. The kernel running on each T640 router's Routing Engine
copies its local forwarding table—which is synchronized with the master forwarding table
by the kernel synchronization process—to all Packet Forwarding Engines in the router.
You can configure PIC-specific features, such as SONET/SDH framing, for specific T640
routers within the routing matrix. For more information about chassis-specific statements,
see the Junos OS System Configuration Guide.
The following is a list of PIC-specific configuration statements that must be configured
for specific T640 routers within the routing matrix:
atm-cell-relay-accumulation
atm-l2ciruit-mode
framing
idle-cell-format
max-queues-per-interface
no-concatenate
To configure chassis-specific features, include the
hierarchy level, and specify the chassis-specific feature to configure.
