VLL resilience for a switched pseudowire path

Figure 1 displays VLL resilience for a switched pseudowire path example. An example configuration follows.

VC switching indicates a VC cross-connect so that the service manager does not signal the VC label mapping immediately but puts S-PE-1 into passive mode, as follows:

configure service epipe 1 vc-switching 
   spoke-sdp 1:100 
   spoke-sdp 4:400
