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
