]3i am trying for a failover between two ISP interfaces using link-monitor in fortigate. both ISP links are vlan interface ( ie, not physical). and with my primary ISP, i have eBGP. i need to monitor the link performance, when packet loss through link, make bgp down, so that traffic will be shifted to ISP 2 ( i have static default route through ISP 2 with higher metric). But in fortigate i have only make interface down ( which is not a good idea obviously) or remove static route through that interface ( which won't work for me, my last mile protocol is eBGP). If any body is able to give any work around, it will be great.
device configuration config system link-monitor edit "to_105" set srcintf "wan" set server "xx.xx.xx.xx" set protocol http set gateway-ip yy.yy.yy.yy set update-cascade-interface enable set update-static-route enable
