PW redundancy — VLL resilience

The following figure shows a VLL resilience path example. An sample configuration follows.

Figure: VLL resilience path

Note:

A revert-time value of zero (default) means that the VLL path will be switched back to the primary immediately after it comes back up.

PE1
     configure service epipe 1
     endpoint X
     exit
     endpoint Y
     revert-time 0
     standby-signaling-master
     exit
     sap 1/1/1:100 endpoint X
     spoke-sdp 1:100 endpoint Y 
precedence primary
     spoke-sdp 2:200 endpoint Y 
precedence 1
PE2
configure service epipe 1
     endpoint X
     exit
     sap 2/2/2:200 endpoint X
     spoke-sdp 1:100 
          standby-signaling-slave

PE3

configure service epipe 1
     endpoint X
     exit
     sap 3/3/3:300 endpoint X
     spoke-sdp 2:200 
          standby-signaling-slave
