Traffic Exchange Services

Each member can exchange traffic with other members through the public peering LAN or through private interconnections.

Public Peering LAN: The public peering LAN is a VLAN that spans all GR-IX points of presence. Each member is, by default, connected to the public peering LAN and is assigned IPv4 and IPv6 addresses for each connection (physical or bundle). These addresses can be used to establish bgp peerings with other members and exchange routing tables (the use of bgp for routing is mandatory in the public peering LAN). In this manner members exchange traffic over the public peering LAN. Please note that each member retains the right to selectively peer with other members, with terms that can be freely negotiated between them.

Route Servers: In order to facilitate the exchange of routing information on the public peering LAN, without the need for bilateral, direct peerings, GR-IX offers two route servers to its members. The route servers simplify the BGP control plane, as each member only peers with the route servers instead of maintaining separate BGP peerings with each member it needs to exchange traffic with. The route servers try to simulate the result of direct BGP peerings by being as “transparent” as possible (e.g. by not appearing in the AS path and by not changing the BGP next-hop of the prefixes). Furthermore, the route servers do not participate in any manner in the data plane of the traffic. The use of the route servers is optional for GR-IX members. Not all members are connected to the route servers; neither are the connected members obliged to exchange traffic with the other connected members. Even for peering through the route server, a bilateral (business-level) agreement may be necessary. Route Servers documentation can be found here (login required).

Private Interconnections: If required, two or more GR-IX members can be directly connected via a separate, dedicated VLAN. Private Interconnections can be used to address special connectivity needs. Please note that the route servers cannot be used in private interconnections.

Colocation Services at ATH01

ATH01 is not a commercial colocation facility; hence members do not have the option to buy colocation services directly from the facility owner. In order to address limited colocation needs, GR-IX offers directly the following services to members connected at ATH01:

Rack Space: Members can lease limited rack space in GR-IX racks (typically, 1-2 rack units). This includes uninterpretable power supply (max. 1 KVA / RU) and cooling, appropriate environmental conditions for telecommunication equipment, IP out-of-band access, console access via terminal server and access to power supply via managed power switch). Please note that due to limited rack space, colocation requests may be rejected.

Fibre Access: The facility can be accessed through two different manholes located right outside of the building, on Vasileos Konstantinou Avenue and on Vasileos Georgiou Avenue.
