Example 3 Forwarding of Tunnel Routing

A company operates two branch offices oversea. Each office deploys a public line to access Internet. Each branch office sets up an individual tunnel with the headquarters to access the corporate Intranet.

Requirements

The LAN links in branch 1 and branch 2 can communicate with each other via the tunnel established with the headquarter.
