Example 4: Central Routing of Tunnel Routing
A company operates two branch offices oversea. Intranet is established throughout the three locations, but the branch 1 does not have any public links to the internet and uses tunnel routing to connect to the internet via the WAN in the headquarters. The branch 2 uses a public WAN link for internet. In the event of WAN link failure, the tunnel between branch 2 and headquarters office will be the backup line for internet connection.
Summary of the Network
| Headquarters | Branch 1 | Branch 2 | |
| WAN 1 | No | 1.1.1.1 | No |
| WAN 2 | No | No | 2.2.2.2 |
| WAN 3 | 3.3.3.3 | No | No |
| WAN 4 | 4.4.4.4 | No | No |
| Headquarters | Branch 1 | Branch 2 | |
| WAN 5 | No | No | 5.5.5.5 |
| LAN | No | 192.168.1.0/24 | 192.168.2.0/24 |
