Guides

Follow these guides in order when bringing up a new CNX connection. Return to the traffic-engineering and member-service guides when enabling optional features.

• Getting started at CNX

  Collect connection details, publish routing data, and prepare routing policy before configuring the IX port.

• Configuring the IX port

  Configure the physical handoff, VLAN, MTU, and assigned IPv4 and IPv6 peering addresses.

• Configuring route-server BGP

  Establish filtered IPv4 and IPv6 BGP sessions with every CNX route server.

• Verifying and troubleshooting peering

  Check the port, BGP capabilities, accepted routes, exported prefixes, and end-to-end forwarding.

• Enabling Add-Path and ECMP

  Receive multiple paths from CNX route servers and install eligible next hops for equal-cost forwarding.

• Steering traffic with communities

  Use CNX large communities to limit propagation, prepend paths, classify routes, and set export MED.

• Publishing routing data

  Publish IRR, AS-SET, PeeringDB, ROA, and ASPA data consumed by CNX routing policy.

• Using the CNX RPKI validators

  Connect an IX router to the IPv6-only CNX RTR service and apply route-origin validation.

• Using the member time service

  Synchronize a directly connected member router over the CNX IPv6 peering fabric.
