How many providers actually apply prefix-based filtering (based on IRR
objects) to other providers?
I like the idea of prefix-based filtering applied to customers (by everyone
that claims to be tier 1 & 2 (&3), at the very least), as well as the idea of
configuring static filters for /19s and such, but if I were to build 46K++
lines of ACLs to filter prefixes from all eBGP peers for all registered
prefixes (from several different registries) .. my routers wouldn't be
manageable.
