An appropriate optical pluggable (SFP, SFP+) for the SIX switch and an appropriate optical patch cable to have connectivity between the optical patch panel at the SIX location and the SIX switch. Contact ARNES for more information on the appropriate optical pluggable and patch cable.
Established BGP peering with both(!) SIX route servers:
BGP peering has to be established between SIX member’s router and both(!) SIX route servers following the condition: one connection to SIX location = one SIX member’s BGP router-id = BGP peering with both SIX route servers.
Established traffic exchange with ARNES.
The SIX Route server only accepts route announcements from the SIX member if they are referenced under the member’s ASN object or under the AS-SET object in the RIPE NCIRR
The SIX Route Server only accepts routes from the member’s BGP router if they have the exact same prefix length as the routes referenced in the RIPE NCCIRR. If, additionally, the member wants to advertise from its BGP router more specific routes with longer prefixes, they must first be added in the RIPE NCCIRR. In general the prefix lengths still accepted by the Route Server are: IPv4: from (included) /8 up to (included) /25 IPv6: from (included) /16 up to (included) /48
Two methods of connecting to SIX
1. Preferred method – SIX member’s router is NOT at the SIX location:
The link between the SIX location and the location of the member’s BGP router has to be based on fibre optics. To ensure quality of the link, only Ethernet pluggables, converters, Ethernet over CWDM/DWDM and Ethernet over SDH or OTN without statistical multiplexing are allowed
Optionally additional Ethernet switches may also be used on the link, provided they are wholly owned and managed by the SIX member. Due to added complexity, usage of Ethernet switches should be avoided whenever possible
Only passive optical equipment and Ethernet optical converters may be installed in the SIX 19” rack. Equipment must be rack mountable
if you are looking for a colocation service in Ljubljana city area, you may found some options here
2. Additional method – router of SIX member is located at the SIX data centre
Limited housing space of total 3 rack height units (HU) – no shelves included – is available per member at each SIX location. If you need more space, we suggest you to contact a few colocation providers in Ljubljana city area and install your equipment outside of the SIX data centre as per prefered method.
Member’s router must be suitable for installation in a 19″ rack
Members have to arrange delivery and installation of their equipment in the SIX premises by prior arrangement with ARNES
Configuration of SIX switch
SIX switches are managed exclusively by ARNES. To ensure safety and stability of the SIX network the SIX switch has the following settings on the interface facing the member’s BGP router:
The interface facing member is statically configured
Each members port is configured to receive untagged Ethernet frames only (access-port only, no VLAN configuration)
Only routers (Layer 3 device) may be connected to the member-facing port
Connecting Ethernet switches in between should be avoided whenever possible
Only one MAC address is allowed on a port, i.e. all frames sent towards the SIX switch should have exactly one unique MAC address
If the SIX switch receives an Ethernet frame from another MAC address or Spanning Tree (BPDU) packet on the member-facing port, the port will automatically shut down temporarily
Configuration of the SIX member’s router
Members must take the following into account when configuring their own router:
On the SIX network only IPv4 and IPv6 Ethernet frames and ARP are required and allowed. Configuration hints and best practices for SIX members are available on the documentation tab of the IXP manager. Access to the IXP documentation page is granted in the process of applying for SIX membership
