• Control plane and data plane

  How route-server BGP sessions remain separate from traffic forwarded across the exchange fabric.

• Add-Path and ECMP

  Why receiving several BGP paths and forwarding over equal-cost next hops are separate router functions.

• Routing security at CNX

  How IRR data, ROAs, AS-SETs, ROV, and future ASPA checks protect route exchange.
