Eliot,Mapping is sourced by the web page. Neither CE nor PE router. The web page allows to change ETR addresses as you like. ETR addresses modification is not related to the ISP connected to customer site. Such web page would be managed by whoever assigned you the EID for your site.
ISP just provides ETR addresses for the PE-CE link. And you do not need to call anyone .. ISP as long as it operates would still announce his block. PE-CE interface you were using will be cleared once you stop paying for the service. That is normal process not much different from today.
I am just trying to avoid additional complexity for no clear gain ... Let me know where is the gap I am missing ...
Cheers, R.

If it is in your CE router, then you have rate*state problems when that line flaps (and we have reason to believe it will flap). If it is in the PE router, I have to call my now former service provider to tell them to stop announcing for me. That's the provider independence part I want. Regards, Eliot
