SD-WAN monitor on ADVPN shortcuts

SD-WAN monitors ADVPN shortcut link quality by dynamically creating link monitors for each ADVPN link. The dynamic link monitor on the spoke will use ICMP probes and the IP address of the gateway as the monitored server. These ICMP probes will not be counted as actual user traffic that keeps the spoke-to-spoke tunnel alive.

• When no shortcut is established:

  # diagnose sys virtual-wan-link health-check
  Health Check(ping):
  Seq(1 tunnel-1): state(alive), packet-loss(0.000%) latency(0.038), jitter(0.006) sla_map=0x3
  Seq(2 tunnel-2): state(alive), packet-loss(0.000%) latency(0.035), jitter(0.004) sla_map=0x3

• When one shortcut is established:

  # diagnose sys virtual-wan-link health-check
  Health Check(ping):
  Seq(1 tunnel-1): state(alive), packet-loss(0.000%) latency(0.039), jitter(0.003) sla_map=0x3
  Seq(1 tunnel-1_0): state(alive), packet-loss(0.000%) latency(0.060), jitter(0.023) sla_map=0x3
  Seq(2 tunnel-2): state(alive), packet-loss(0.000%) latency(0.035), jitter(0.002) sla_map=0x3

• When more than one shortcut is established:

  # diagnose sys virtual-wan-link health-check
  Health Check(ping):
  Seq(1 tunnel-1): state(alive), packet-loss(0.000%) latency(0.036), jitter(0.004) sla_map=0x3
  Seq(1 tunnel-1_0): state(alive), packet-loss(0.000%) latency(0.041), jitter(0.009) sla_map=0x3
  Seq(2 tunnel-2): state(alive), packet-loss(0.000%) latency(0.030), jitter(0.005) sla_map=0x3
  Seq(2 tunnel-2_0): state(alive), packet-loss(0.000%) latency(0.031), jitter(0.004) sla_map=0x3
