- Limit 10
- IPv6 prefixes
- Limit 20
- Filtering
- RPKI + IRR (AS-SET)
- Tunnels
- GRE / WireGuard / OpenVPN
Requirements
- A publicly routable, unique ASN and a router capable of running BGP
- Complete and accurate PeeringDB profile; NOC contact at session establishment
- Adhere to the technical requirements of each exchange
