My current firewall seems to be able to support using CLI
but I want to do using GUI.

Link monitor is used to remove routes from routing table in case one link (interface) fails.
I don't quite understand your requirements here or what are you trying to accomplish
It is very simple.
Same as Cisco.
IP sla to track 8.8.8.8.
When vrrp fails the IP sla, it decrements the priority.
This is standard setup.
You have given me links for vrrp. But not how to integrate priority decrement and IP sla with vrrp. Just like a Cisco config.

Be aware FGT's VRDST "monitor" is not the same with Cisco's IP SLA as the KB @heng provided the link to is describing. It monitors only kernel routing table to see a match. Never sends out ping to the server IP.

If it is such as a serious issue. You should bring it up to the r&d. Not everyone reads this forum.
If it doesn't do active ping how does it check that the link is down?
What is the purpose of link monitoring then?
Then how is it supposed to detect that the link is down without probes?

If the link goes done all routes bound to the link will be removed. That's how VRDST route removal can be detected. A possible issue is if another route that covers the VRDST, such as 0/0, is coming from or bound to another link with a lower precedence, it won't see it as down. There are some options to mitigate that and the link @heng pointed shows one option.

Hi,
There are few KBs that described the the usage for the link monitor + VRRP failover. Please take a look, thanks.

Also there is no set vrrp or config vrrp in my interface mode.
What should i do?
hi,
Can you post your snippet config here with ? when you are under system interface.
Also, what is your FGT model?

I solved it. Wrong type of interface.
I am more concerned with what tochi is saying above.
