Monitor next hop on each link

I have two configured links. Each link goes to a separate router, and each router goes to a different ISP.

 

 

How can I have the F5 do a check on the next hop outside of my network (1st hop at the ISP) to verify the links are functioning?

    You need to use a transparent monitor configured with the destination IP of that next hop. Then apply that to the pool members in your gateway pool.

    hi sose -

     

     

    You can use what we call a transparent monitor for that.

     

     

    Check out this AskF5 solution for details:

    So I configured a node specific health monitor for the link I want to check. It is configured as a transparent monitor as suggested. When applied to the node, the node properties window shows no health monitors listed in the top general area, even though at the bottom I have selected this monitor. Any thoughts?

     

     

    Seems kind of strange to me that this is not something that can be done on the link level.

     

     

    Thanks for the help!
