Members can connect to SGIX using one of more physical connections and reach many other peers on the peering fabric, thus optimizing the cost per peer when exchanging traffic between different networks. Ports available are 1G, 10G and 100G for traffic exchange.
Members can implement OPEN or SELECTIVE peering policy or a combination of both where different sets of prefixes are announced to OPEN and SELECTIVE peering group.
OPEN PEERING POLICY
Also known as Multi-Lateral Peering (MLP) policy where members peer with all other members in the IX via a single BGP session with SGIX Route Servers (RS), which function like a transparent eBGP route reflector. Members can control their prefixes announcement to other members by tagging them with SGIX BGP communities. By default, RS will advertised all prefixes to all peers.
SELECTIVE PEERING POLICY
Also known as Bi-Lateral Peering (BLP) policy where member setup direct peering with each other according to their own requirements.
