The heart of the Peering.cz IXP represents a fully redundant 100GbE backbone.
For peering between networks, we use the reserved peering segment 220.127.116.11/24 for IPv4 and
2001:7f8:7f::0/64 for IPv6.
We offer all connected entities the possibility of creating a private VLAN that can be spread across all PoPs.
Connections can be made using 10, 40, 100 and 400GbE ports.
For common traffic we use public peering VLAN.
Our backbone is built on network elements by Arista Networks.
Peering.cz platform is being monitored 24/7 by our NOC.
Route servers make administration of routes easier.
Peering.cz operates two route servers to facilitate a redundant setup for multilateral prefix
announcements between peers.
You don’t need any additional bilateral agreements with networks connected to our route
servers. With every new route server participant, you will automatically exchange prefixes
unless you have filters set.
You don’t need to maintain BGP sessions with each participating peer. Connect to other peers
on the route servers by creating one BGP session towards each route server to directly access
all networks peering with them.
Peering with our route servers can be set up via Peering.cz ASN - AS61195.
Announcements via route servers are filtered based on filters automatically generated from
corresponding IRRdb (i.e., RIPE, ARIN).
You can control BGP announcements via BGP Communities.
We use two basic types of communities - Action and Info. Action Communities allow you to
control route advertisements. Info Communities can be used to distinguish country of origin,
PoP of origin, etc.

Note that route servers don’t add their ASN to the AS_PATH. You will need to configure your
router not to enforce the first ASN to match the Peering.cz AS61195.
Allowed Protocols and Traffic
No L2 protocols that could negatively affect node operation (STP, LLDP, CDP, etc.) are allowed on client ports.
Broadcast communication towards Peering.cz ports is not allowed. Multicast is only allowed via separate VLANs.
All newly connected ports are first placed in the so called quarantine VLAN to ensure proper
settings before switching to live production.
