WAN link Failover

Hi All, Currently having an Fortigate 500E running in A-A cluster, where each cluster unit connected to 3 Different ISP via WAN Switch Here Wan Switch in stack works just as a L2 Vlan for Each ISP Public IP Example: Airtel ISP public IP - 1.1.1.2/30 assign Vlan 10 Sify ISP public IP - 2.2.2.2/30 assign Vlan 20 TCL ISP public IP - 3.3.3.2/30 assign Vlan 30 Here the configuration I'm doing on fortigate to achieve if one ISP link goes down internet traffic will shift to another ISP #config system link-monitor edit Wan1Failover set srcintf port1 set server 8.8.8.8 set protocol ping set gateway-ip 1.1.1.1 set source-ip 0.0.0.0 set interval 5 set timeout 1 set failtime 5 set recoverytime 5 set ha-priority 1 set update-cascade-interface enable set update-static-route enable set status enable next edit Wan2Failover set srcintf port2 set server 8.8.8.8 set protocol ping set gateway-ip 2.2.2.1 set source-ip 0.0.0.0 set interval 5 set timeout 1 set failtime 5 set recoverytime 5 set ha-priority 1 set update-cascade-interface enable set update-static-route enable set status enable end So my question is would I need to specify source ip as set source-ip 0.0.0.0 in above command or I can specify my wan interface IP I.e (1.1.1.2) in place of 0.0.0.0 Also need to know why below command required to achieve failover of ISP set ha-priority 1 set update-cascade-interface enable Any help will be appreciated
