Example:Configuring Ethernet LFM for CCC
Inthis example, LFM is configuredbetween two PEs (PE1 and PE2) connectedusing CCC.
WithLFM in place, a link fault will be detectedimmediately, instead of depending on
routingprotocols to find the fault on end-to-endCCC connection. This also helps in
detectingtheexact failed link instead of onlyfinding that the end-to-end CCC connectivity
hasfailed. Also, because LFM runs atthe link-layer level, it does not need a IP address
tooperate and so can be used where bidirectional faultdetection (BFD) cannot.
Thelinks running LFM are shown in Figure 20 on page 139
