LSIX Route Server Guide

About Route Servers

LSIX operates route servers to facilitate the exchange of BGP learned routes between different members on the peering platform. To exchange and learn routes from all other members on the route servers, each peer needs to setup only one BGP connection to one or multiple of the LSIX Route Servers.

The LSIX Route Servers operate on servers running the BIRD routing daemon.

RFC7947 of the Internet Engineering Task Force (IETF) describes the specifications and properties for the implementation of a route server in more detail.

BGP Session Information

Hostname IPv4 IPv6 ASN
rs1.lsix.net 185.1.32.254 2001:7f8:8f::a504:9917:1 49917
rs2.lsix.net 185.1.32.253 2001:7f8:8f::a504:9917:2 49917

BGP Recommended Settings

Max Prefixes IPv4 Max Prefixes IPv6 RIR MACRO IPv4 RIR MACRO IPv6
100,000 50,000 AS-LSIX AS-LSIX-V6

BGP Prefix Filtering

The LSIX Route Servers are setup with route automation settings. Every 24 hours our route servers generate a list of allowed prefixes per autonomous system number and applies those to the active filters on the route servers.

Example Configurations

The only required protocol on the exchange is BGP. Make sure you disable any other protocols on the port(s) facing the peering platform such as OSPF, ISIS, LLDP and STP.
