| remarks | The following is required to share a BGP session with |
| remarks | AS51088: |
| remarks | - The customer's gateway router must be using BGP v4. |
| remarks | - The customer must use a RIR assigned ASN. |
| remarks | - The customer must have its customer-routes registered with |
| remarks | an instance of the IRR. Its 'as-set' must include the ASNs |
| remarks | originating routes and for each route exported a relevant |
| remarks | 'route' object is required. |
| remarks | - The customer must export its customer-routes reasonably |
| remarks | aggregated, and AS51088 will not accept any prefix that is |
| remarks | longer than a /24 (except for denial-of-service mitigation). |
| remarks | - The customer may use MED to signal its return path pre- |
| remarks | ference in AS51088. |
