Mission 021

Engineer Briefing

A network engineer has successfully built a Local Area Network.

Inside the network:

PC1

 |

Switch

 |

PC2

Devices can communicate using:

• MAC addresses.
• Ethernet frames.
• Switch forwarding.

However, real organizations are not built with only one network.

A company may have:

                 COMPANY NETWORK

        Sales Network

        192.168.10.0/24

                |

        Administration Network

        192.168.20.0/24

                |

        Server Network

        192.168.30.0/24

These are different networks.

A switch can connect devices inside the same network.

But what connects:

192.168.10.50

to:

192.168.20.50
