Can you be a bit more specific about the config?
This is presumably an eBGP session across a local interface?
What platform& IOS version?
eBGP sessions should, IIRC, be immediately torn down by the fast
external fallover feature.
If it's an Ethernet though that won't do much since the link is likely
always staying up/up.
That depends entirely on the topology. If there's an intermediate
network device, then yes. But that's a bad configuration, and should be
avoided if at all possible, for exactly that reason.
Obviously point-to-point ethernet will fail the link almost immediately
if either end goes down.
