The Routing Engine (shown in Figure 16 on page 29) is a two-board system with the
following components:
CPU—Runs Junos OS to maintain the router's routing tables and routing protocols.
DRAM—Provides storage for the routing and forwarding tables and for other Routing
Engine processes.
CompactFlash card—Provides primary storage for software images, configuration files,
and microcode. The drive is a fixed CompactFlash card and is inaccessible from outside
the router.
Hard disk—Provides secondary storage for log files, memory dumps, and rebooting the
system if the CompactFlash card fails.
