Route server details:

  • General info on route servers is at AMS-IX Route Servers.
  • The SIX ASN is 33108.
  • Max prefix for IPv4 and IPv6 comes from your ASN's PeeringDB record. For your peering, if you use a max prefix with the route server, we recommend 100,000 for IPv4 routes and 30,000 for IPv6 routes.
  • IPv4 routes shorter than /8 are filtered and IPv6 routes shorter than /19 are filtered. Bogon ASNs and martian prefixes are filtered.
  • Strict filtering is performed using Internet Routing Registry data. IRR Explorer may also be useful. You can verify your RADB data with:
    IPv4 prefixes: whois -h whois.radb.net '!gasYOUR_ASN_NUM'
    IPv6 prefixes: whois -h whois.radb.net '!6asYOUR_ASN_NUM'
    AS-SET ASNs: whois -h whois.radb.net '!iYOUR_AS_SET_NAME'
  • The route servers are configured to be passive. If you have a PeeringDB record and IRR records, you are ready to peer with the SIX route servers. Your PeeringDB "IRR Record" should contain simply your IRR as-set name. The route servers use this information. (Please no colons in your as-set name. If you must have a colon, email info_a_t_seattleix.net for special handling.)
  • IRR Setup tutorial.
  • The route server service is intended to supplement, not replace your direct peering. If you have a peer you value, take the time to establish direct peering.
  • It is important to establish sessions with all of the route servers available on the VLANs to which you are attached, so that maintenance on one route server does not affect your connectivity.
  • The communities specified in the table below may be used to control the propagation of your routes. In addition, the RFC 7999 BLACKHOLE community 65535:666 is supported. See our blackholing page for additional details.
  • The route server software is BIRD. Much appreciation to the BIRD team.
  • BGP passwords (RFC 2385) are not supported.
  • Jumbo VLAN participants: You may want to prefer the jumbo VLAN for equal paths received from both VLANs. One way to do this is with MEDs (external metric) since that will not override AS path selection.
  • Write to info_a_t_seattleix.net to trunk your circuit to gain access to the Jumbo VLAN.
  • A looking glass for prefixes sent to the route servers is available for each participant at the participants page, including the reasoning behind any prefixes dropped by the filters. Data may be a minute or two old.
