VLL resilience

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

Figure: VLL resilience

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

Example: PE1 configuration

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

Example: PE2 configuration

configure service epipe 1
endpoint X
exit
sap 2/2/2:200 endpoint X
spoke-sdp 1:100 
standby-signaling-slave

Example: PE3 configuration

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