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.
