honoring AS-path prepend from a peer or customer?
If a peer (or transit customer) prepends their own AS to their route announcements to you, do you ever strip off the excessive As'es? That is, do you always honor them in your announcements to your other customers (or peers)? I do understand that any operator has full control over deciding his own outbound policy, regardless of the AS path. I want to know what the industry practice is and whether I should stipulate in my next upstream agreement that they honor my prepends? Thanks.
