Another finding... A solution? I see that I receive a lot of non-terminated traffic. Meaning a packet for an IP that does not exists (about 10% inbound) Apart from setting up ingress(?) filtering to ensure that these packets gets dropped before they go further, I need to communicate with my upstream provider to ensure that he/she drops these packets too before they go on my link. Is there a way to automatise that, so a soft can talk to my upstream provider network system and automatically inform him on which IPs are terminated? Routing protocol aggregates IPs, so I'm not sure it may select only valid IP and not a range where some IPs are valid... Is something like that exists or a new RFC is needed?
