Hello Mark,
Thanks for asking. This is eBGP and the issue is that there have been
failures whereby the link does not fail, and thus can't track that
routes should be removed. BGP session has stayed up in some cases as
well, yet no traffic.
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.
Mark.
