Do Cisco routers use Linux?

How does Linux routing work?
Routing decisions are fairly simple for most hosts:
- If the destination host is on the local network, send the data directly to the destination host.
- If the destination host is on a remote network that is reachable via a local gateway listed in the routing table, send it to the explicitly defined gateway.
