FIBTELIX is a virtual IXP. Participants connect over VXLAN or GRE tunnels instead of physical cross-connects. Set up a tunnel, establish BGP, and start peering.
No rack space, no cross-connects, no waiting. Your tunnel terminates on a shared Linux bridge that forms the peering LAN.
Choose VXLAN or GRE. Your endpoint only needs a public IP and a route to our server. Tunnels terminate in a common bridge — the peering LAN — so all participants share one broadcast domain.
Two route servers running BIRD 2. RPKI validation rejects invalid origins. Per-peer IRR prefix lists are rebuilt every 6 hours via bgpq4. Bogon prefixes and ASNs are dropped.
Operated by Fiber Telecom s.r.o. No fees for participants. Transit to NIX.CZ is available through the group. You just need an ASN and public address space.

The whole process usually takes a few hours.
Email [email protected] with your ASN, preferred tunnel type (VXLAN or GRE), your public endpoint IP, and your AS-SET if you have one registered in IRR.
We check your ASN registration, IRR objects, and RPKI ROAs. Once approved, you receive a peering LAN address and tunnel configuration details.
Configure a VXLAN tunnel (VNI 100, dport 4789) or GRE tunnel to our endpoint. Assign the peering IP we gave you to the tunnel interface.
Peer with both route servers at 185.1.173.1 and 185.1.173.2. IPv4 and IPv6 are both supported. Once the session is up, you'll see routes from other participants.
