The Route Servers (RS) are used to facilitate interconnection between LL-IX participants and exclude the need to establish a BGP session with each LL-IX participant individually. Route Servers retransmit BGP announcements between the connected parties,  thus peering via RS allows establishing connection with all the participants connected to LL-IX RS. Once the BGP session is established, IP traffic is exchanged transparently between BGP neighbors on the peering LAN.

Connection to RS servers takes place via BGP protocol (RFC 4271) and can be installed with one or more RS servers where a physical connection to LL-IX equipment port is located.

The announcements received by the LL-IX servers are filtered according to the following rules:

  1. Do not accept announcements in which the Origin field does not match the same field of the Route/Route 6 object in the IRR database (RIPE or RADB), or in case the Origin is not listed in the corresponding AS-SET object;
  2. The announcements of the networks listed in RFC1918 are not accepted;
  3. The Default Route is not accepted.

The IX members receive the routes that are the best among those received from all the peers. The IP address of the peer that announced this best route is transmitted as a Next-hop. The AS Path attribute is passed unchanged. In order to manage routing announcements regarding other IX participants a BGP community list is used. This list allows extending the path announced to a certain IX participant, as well as to filter the prefix announcements to a certain peer.
