Mutually Agreed Norms for Routing Security

Requirements for Participation

By joining, you support and commit to the baseline of routing security defined by a set of six security-enhancing actions, of which five are mandatory to implement.

The actions are:

  1. Prevent propagation of incorrect routing information (mandatory)
    1. Baseline Requirement: Ensure correctness of own announcements. Ensure correctness of announcements of their peers (non-transit) and customers by implementing explicit (allow-list) filtering with prefix granularity. (mandatory)
    2. Additional requirements: Participants can further indicate they comply with one or both of the following additional requirements of Action 1: the use of RPKI as a primary source of validating information, and the use of a Standard AS-SET Expansion Process. (recommended)
  2. Prevent traffic of illegitimate source IP addresses (mandatory)
  3. Facilitate global operational communication and coordination (mandatory)
  4. Facilitate validation of routing information on a global scale (mandatory)
  5. Encourage MANRS adoption (mandatory)
  6. Provide monitoring and debugging tools to peering partners (recommended)
