Frequently Asked Questions
Q— I have an SF hub and an SJ hub. Do you think it is better to separate them into different ASs and run BGP instead of running an IGP in between?
A— This doesn't sound like a candidate for segmentation via BGP. Remember that even though segmentation gives better hierarchy and control, it introduces more routing policies dictated by BGP's behavior. In small networks such as yours, you could achieve the same stability by performing adequate hierarchical routing using an IGP.
Q— I do not have enough BGP peers to justify using route reflectors. What happens if I use them anyway?
A— You will achieve normal routing. You just need to understand that with this model, you need to rely on the centralized routers to forward ...
