If you suspect that an installed software process is not running, you can check the<br />

process. Here, we check for RPD, the routing-protocol process:<br />

aviva@router1> show system processes | match /rpd<br />

We see that RPD is not running. Because the Routing Engine and the forwarding<br />

plane in JUNOS routers are separate processes, even when RPD is not up, the router<br />

continues to operate and forward traffic. However, it cannot perform any routing<br />

operations, such as sending routing-protocol updates and maintaining the routing<br />

table.<br />

When you need to find out what hardware is installed in the router, use the show<br />

chassis hardware command. The first column of the output lists each hardware component<br />

installed in the router, starting with the chassis, which is the router itself.<br />

This router, an M20 system, has one power supply, two Routing Engines, one<br />
