Technical Information
Built for the network engineers who run it
Everything you need to plan a connection to CSRAIX — supported interfaces, route server policy, filtering requirements, and sample configurations for common platforms.
Interfaces10G SFP+, 40G QSFP+, 100G QSFP28
Routing ProtocolBGP-4 (multihop not supported)
Address FamiliesIPv4, IPv6
Route ServersBird-based, dual RS for redundancy
IRR FilteringRequired — RADB, ARIN, or regional IRR
RPKI ValidationROV enforced at the route server
Max Prefix Limit100 IPv4 / 20 IPv6 (default, adjustable)
BGP Communities65000:1 (learned from RS1), 65000:2 (RS2)
AS Number Requirements
Before you apply
- A registered, publicly routable ASN
- Accurate, up-to-date PeeringDB record
- Correct route/route6 and as-set objects in an IRR
- A published NOC contact reachable 24/7
Connection Requirements
Physical & session requirements
- 10G SFP+ (LR or SR, facility dependent) hand-off
- Single MAC address per port — no bridging or NAT onto the exchange VLAN
- BGP session with each route server (recommended) and/or bilateral peers
- MTU of 1500 unless otherwise arranged
Sample Configurations
Route server peering, by platform
Reference configurations for a single route server session. Adjust ASNs, addressing, and filter names to match your network.
