We use them..
as you say for customers only. Inter-provider we have basic bogon checking plus
maximum prefix. Its too unwieldy to build when you have peers exchanging
thousands of routes... theres a belief that the peer should be behaving
responsibly tho and this is a condition of most bilateral peering contracts.
Going back to the original topic on this thread I would expect a deliberate
attack on BGP routing to come from a customer not a provider such as Level3, if
they are filtering in turn to their customers we have a reasonable amount of
sanity checking going on
