What is MANRS

Mutually Agreed Norms for Routing Security (MANRS) is a global initiative, supported by the Internet Society, that attempts to reduce the most common routing threats.

MANRS outlines four simple but concrete actions that network operators should take:

  • Filtering – Ensure the correctness of your own announce­ments and of announce­ments from your customers to adjacent networks with prefix and AS-path granularity
  • Anti-spoofing – Enable source address validation for at least single-homed stub customer networks, your own end-users, and infrastructure
  • Coordi­nation – Maintain globally acces­sible up-to-date contact information
  • Global Validation – Publish your data, so others can validate routing infor­mation on a global scale

A separate set of Actions applies explicitly to Internet Exchange Points.

GRNOG supports MANRS
