I'm not sure of the intent of doing the above, at least if when we are
speaking of a Cisco it is specific to their router product line.
Perhaps if you could draw a diagram or explain what you mean
in more detail it would help me to understand.

This is what I meant, since I expect it is the most common use of
the router "APS" functionality. Unless something has changed in the
last year or two (which is entirely possible, I don't actually touch routers
much these days), the keepalive protocols used by Cisco and Juniper
to track which router is "working" and which is "protect" are different,
so one vendor's product can not back up the other's.
