Is it possible to create an applet that would monitor a remote ip address and then perform an action based on that reachability?
What I have is something like this:
I want to be able to monitor RTRC's reachability to RTRD, but I need to do it from RTRB. You can't see it above, but RTRA also connects to RTRD. If RTRB can't get to RTRD through RTRC, I want RTRB to apply a policy map in the direction of RTRA because traffic will get redirected. Is this possible to do, or is there a better way of doing that?
