OTOH, if you are single-homed, it is highly advisable to accept a default, the reason being that most transit providers provide bgp communities with "don't advertise to customers" semantics. So if you're single-homed and use a full dfz feed without default route, you will not have full connectivity to all the routes available from the transit provider.
If you are single-homed, there is no need for BGP at all. And injecting your ASN into the table is probably not terribly useful to everyone else’s FIB. There are, of course, corner cases. But in general, single-homed people shouldn’t be using BGP. -- TTFN, patrick
