Operation of master-slave pseudowire redundancy with existing scenarios

This section describes how master-slave pseudowire redundancy could operate.

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

Figure: VLL resilience

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
