Scenario Analysis
Create tunnel A through a dynamic signaling protocol. The tunnel path is Router A -> Router B ->
Router C -> Router D. In this tunnel, the link between Router B and Router C is to transmit important
service data, therefore required to be protected. Create tunnel B through a dynamic signaling
protocol. The tunnel path is Router B -> Router E -> Router C. Tunnel B can well protect tunnel A.
Once the link between Router B and Router C fails, tunnel A's path will change to Router A ->
Router B -> Router E -> Router C -> Router D.

Application Scenario
A company has five offices, office A through office E, which are connected with one another
through networks. It is required to protect the link between office B and office D. Once the link
fails (for example, the device in office C fails), data packets can be forwarded quickly through
another path, and, after the link resumes, data packets can be forwarded through the link again.
