...again, I'm confused. BGP updates from where to where? From how I understand the OP's original question, there is no BGP. Hence, if one of the providers is statically routing the prefix to an interface or un-numbered as opposed to an IP address, then blackholing can occur if IP reachability is broken, but the link-layer is not. Is this not correct? Steve
