MX80 Routing Engine Description
The Routing Engine is built-in on the MX80 base board and cannot be replaced.
The Routing Engine consists of the following components:
- Processor—Runs Junos OS to maintain the router's routing tables and routing protocols.
- DRAM—Buffers incoming packets and provides storage for the routing and forwarding tables and for other Routing Engine processes. To view the amount of DRAM installed on your router, issue the show chassis routing-engine command.
- NAND flash—Provides primary storage for software images, configuration files, and microcode.
