Example: Configuring Ethernet LFM for CCC

In this example, LFM is configured between two PEs (PE1 and PE2) connected using CCC.
With LFM in place, a link fault will be detected immediately, instead of depending on
routing protocols to find the fault on end-to-end CCC connection. This also helps in
detecting the exact failed link instead of only finding that the end-to-end CCC connectivity
has failed. Also, because LFM runs at the link-layer level, it does not need a IP address
to operate and so can be used where bidirectional fault detection (BFD) cannot.

The links running LFM are shown in
