Yes bgp multihop is a GREAT* way to figure out if a cablemodem** is even
/really/ online.
Alas, I've not see much on the traffic engineering side either.
* Read "the only way i've found to do this with cisco's ios"

Subject: On the subject of multihoming
I'm working on a small experiment which utilizes multiple outbound links (in
the experiments case multiple consumer 3G connections [to 2 Sprint/2
Verizon/1 AT&T], Time Warner Cable Modem and an SBC Global DSL connection.
What is the best way to do outbound traffic engineering? I would like to be
able to determine the best path possible and send traffic out the appropriate
link.
Could this be done with a copy of the BGP tables?
Obviously as they are consumer connections, I wouldn't get a BGP feed so
would need to download a copy, which has the risk of stale data. Perhaps some
sort of multihop BGP setup?
I have done some research and found a lot of references to small site
multihoming without BGP for link redundancy but not for traffic engineering.
Thanks.
