Action 1: Prevent propagation of incorrect routing information
1 - Ip prefix filters
2 - AS-path filters
3 - Community filters (in) (Out)
Action 2: Prevent traffic with spoofed source IP addresses
We apply ACLs to the interfaces with clients where only traffic from the network provided to the client is allowed.Where the network PE allows it, we apply antispoff rules directly to the interface made available to the client.
Action 3: Facilitate global operational communication and coordination
Keep the information updated in the peering db
Action 4: Facilitate validation of routing information on a global scale
We have implemented a lookglass in our network.
