I was thinking to ask the following question to my provider, hoping to get an answer How robustly architected is the MP-BGP? How fast is convergence?BGP times ? scan timeres in and out? What IGP is the provider using in their core? What bandwidth they gonna guaranteed ? As you said the convergence time is a real factor?
