[AusNOG] Inbound BGP traffic balancing

[Mark Newton]

Other than the aesthetic purity of a finely-mirrored Graphana plot, is there a business reason for wanting it 50/50?

BGP isn’t designed as a load balancing algorithm. And most people have a carrier that’s better than the others anyway, and it’s normal to set up routing to give that one the traffic.

What’s the point of wanting a 50/50 mix? What’s wrong with 90/10?

If you answer those questions, you might get some more worthwhile responses.
