He already said it's way upstream... no local enough bfd wont help.

I consider GOOGLE's anycast dns 8.8.8.8 the gold standard - if my sla's to ping 8.8.8.8 fail - it kills the bgp neighbor.

This is just a simple sla & track object, with a static route to google's 8.8.8.8 in my router to my ISP's other side of our directly connected /30 (recursive). Then my static route to my bgp neighbor uses the tracked object - if tracked object is down, route to neighbor is down, routes from neighbor go away.

Looks like your ISP needs its engineers to do the Service Provider Operations Lab, huh? They suck...

What about BFD between your CE routers and the PE Routers.
Most providers will support it for fast reconvergence.
