Route servers facilitate Multilateral Peering. A single BGP session with each route server allows you to see the prefixes of all of the other networks peering with the route servers. The route servers preserve the sending peer's next-hop and other prefix attributes. No traffic is ever routed by the route servers, they simply facilitate prefix exchange. Connecting is free - there are no additional fees charged for using this service.
LONAP operate two route servers, running different releases of BIRD
We offer two route servers for resilience, so please turn up a session to both. Having two servers allows us to perform safe upgrades and maintenance on the platform without interrupting service.
- RS1 - AS 8550 : 18.104.22.168 / 2001:7f8:17::1
- RS2 - AS 8550 : 22.214.171.124 / 2001:7f8:17::2
LONAP permit participants on the route-servers to filter their announcements such that they are not offered to certain other peers on the route servers. This is useful if you wish to prevent your prefixes from reaching your transit customers via the route-servers, or if you do not wish to peer with some networks as a matter of policy. The filtering logic is expressed with the use of BGP Communities:
- 8550:8550 - Send prefixes to all other route-server participants
- 8550:ASN - Send prefix to only route-server participant with specific ASN
- 0:ASN - Do not send prefix to route-server participant with specific ASN
- 0:8550 - Do not echo prefix to any other route-server participants.
The default behaviour if no communities are specified is to advertise all prefixes to all peers.
The well-known community NO-EXPORT (65535:65281) is not processed by the route server, but is passed transparently to peers. Setting NO-EXPORT specifies that your prefixes will advertised to LONAP Peers, but that peers should not advertise to downstream or other external ASNs.
The community logic is identical for IPv4 and IPv6 peering. The LONAP route servers support IPv4 and IPv6 prefix exchange.
You must register any prefixes that you send to the route-servers in a public routing registry database, ideally one that is mirrored to RADB. For most of our members, this means 'please register route objects in the RIPE database for your prefixes' (and encourage your customers to do the same). Any prefixes which are not properly registered with route objects will not be accepted by the route servers.
Most members will want to send their prefixes to the route servers, and tag community 8550:8550 with them. Here is an example Cisco configuration which achieves this.

We recommend that any network with an open multi-lateral peering policy, do connect to the route-servers.
To connect, you need to request that LONAP support configure your route-servers sessions. Please email support-at-lonap-dot-net to reach this team.
There are many tools and integrations available for automation and router configuration with peeringDB.
We also support the IX-F JSON export schema. Further details are in the Documentation section in the LONAP Portal (login required).
We automatically update various RIPE objects. Further details are in the Documentation section in the LONAP Portal (login required).
