John,

I disagree.

Why couldn't you prepend your own AS several times to the routes within your
control that you want to look less attractive for whatever link you don't
want them to take and then advertise that back out to your ISP. That should
make the other link look more attractive to incoming traffic having less
hops to your AS.

I agree with John on this one - there is nothing you can do to influence
which inbound path a packet will take. I say try the cash option!

The way I see it--Outbound policy is completely within
your control. Inbound policy unfortuantely is not. The
best you can hope for is to provide a "hint" to the
neighboring AS. If that AS decides to take the hint
then you are fortunate.

If that administrator will not cooperate you can
always try cash! ;)

Cheers,
John
