If I have 2 possible outbound paths, 1 primary, 1 secondary, and I obviously need the secondary to come up if the primary fails. The problem I am foreseeing though, if the RF signal fails, the links will stay up because there are RF devices between them.
From router2 perspective, the link to router1 stays up/up even if the RF signal fails, and it will never fail over to Link 2... (R1 on left, R2 on right)
is there any way to have router2 track actual connectivity (not just the up/up link) to router 1 and have it fail over if it cannot reach it.
Would a routing protocol easily fix this situation? The bottom link does not yet exist, I want to theory craft this first.
