Action 1: Prevent propagation of incorrect routing information
Specific-prefix outbound filtering of our network to peers and upstreams using Internet Routing Registries (IRRs) and we require to our customers to register route objects
Action 2: Prevent traffic with spoofed source IP addresses
Specific firewall filtering allowing only legitimate ip addresses to go out of our network
Action 3: Facilitate global operational communication and coordination
Publishing our contacts on RIPE DB and PeeringDB
Action 4: Facilitate validation of routing information on a global scale
