rfc 4893 (4 octet as numbers) leverages the assumption that you can send the as4_path attribute and that even router's that don't understand it will forward it. given that 4 byte as numbers exist in the internet and many non-4byte aware routers exist, that seems like a reasonable assumption. > > Bjørn > >
