Yeah, if the physical media is unable to indicate link-layer failure to 
the system, BFD is probably you best bet at detecting link failure.

Have you worked with your eBGP neighbor (I'm guessing your transit 
provider) to see what they can do to improve link failure detection at 
the link layer? Perhaps avoid an intermediate Ethernet switch between 
both your routers, e.t.c.
