As much as it would be nice if everyone used prefix-lists on their customer BGP sessions, but sometimes this is not possible, or cumbersome. I know from past experience as a transit customer, that I have personally shyed away from ISP's that have restricted me to having their NOC update my ACL.
But instead you prefer a "lazy" NOC, where you need manual intervention in case you screw up a filter list on your end to re-enable the BGP session?
No, instead I prefer to do all route filtering on my (cust) side, and have the ISP do filtering based on AS PATH, be it ^CUST-AS_ or configured off the RADB...... It's been my experience that a lot of the providers that do prefix filtering on customer BGP sessions take great amounts of time before they act on the prefix-filter update request. This much fun when it's 5pm or later and you really need to announce a new customer netblock. Joe
