Listen "Rethinking BGP on the DC Fabric (part 5)"
Episode Synopsis
BGP is widely used as an IGP in the underlay of modern DC fabrics. This series argues this is not the best long-term solution to the problem of routing in fabrics because BGP is not ideal for this use case. This post will consider the potential harm we are doing to the larger Internet by pressing BGP into a role it was not originally designed to fulfill—an underlay protocol or an IGP.
My last post described the kinds of configuration required to make BGP work on a DC fabric—it turns out that the configuration of each BGP speaker on the fabric is close to unique. It is possible to automate configuring each speaker—but it would be better if we could get closer to autonomic operation.
