Monitoring Status of a Pool on another LTM

We currently have a solution we're trying to design which has the dependency on an "Upstream" BIGIP having access to the internet. A very simple diagram being

 

BIGIP02 -> 3rd Party Proxy -> BIGIP01 -> Internet Router

 

What would be the best/easiest way to do this?

 

The router will be monitored with a simple TCP Check to see if its available,

 

I was thinking of setting a VIP up on BIGIP01 that BIGIP02 Checks, if the pool assigned to that VIP (The Router's health check) Fails, the router will be taken offline, and the VIP will not respond.

 

Of course the VIP on 01 will be a pool on 02 with a monitor assigned.

 

Any thoughts appreciated. Regards,

    Is the 3rd party proxy IP-based? Such that you have to define the pool on BIGIP02 to point to it, which then points to BIGIP01? If so, one thought is to create your BIGIP02 pool to be "transparent". Enable the Transparent option in your monitor and then specify an alias address - the address of the BIGIP01 VIP.
