8.18.5 Example for Associating Ethernet CFM with an Interface

In this example, by associating Ethernet CFM with an interface, you can detect a fault on the
link between a CE and a UPE through LACP.
Networking Requirements
As shown in
Router B. Router A acts as the CE device. Router B acts as the UPE device. It is required that
the following be achieved:

Figure 8-20, a user network is connected to an ISP network through Router A and
The bandwidth for the user network to access the ISP network is 2000 Mbit/s and an inactive
link that serves as a backup is provided.
When the active link between the user network and the ISP network fails, the LACP module
on the interface can sense the fault within 50 ms and stop forwarding data on the active
link.
