Whether anyone likes it, it has become a TE knob of sorts, in a protocol with few such knobs, and many smaller transit providers rely upon it to affect route selection for non-malicious reasons, such as to balance their own transit links. Without providing an alternative, it will be crippling to many to inhibit its use as such. _______________________________________________ sidr mailing list sidr@ietf.org https://www.ietf.org/mailman/listinfo/sidr
