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.

GR-IX supports MANRS

MANRS requires from Internet Exchange Points to implement the following:

Action 1: Prevent propagation of incorrect routing information
Action 2: Promote MANRS to the IXP membership
Action 3: Protect the peering platform
Action 4: Facilitate global operational communication and coordination between network operators
Action 5: Provide monitoring and debugging tools to the members

GR-IX adheres to all of the MANRS principles above and considers the role of Internet Exchanges in reinforcing routing security crucial. For that reason, GR-IX supports the MANRS initiative and has joined the MANRS programme since May 2018.

MANRS for Operators

GR-IX strongly encourages its members to join MANRS. 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
