Hi Scott, How are you configuring vpp? Through binary API or with commands?
Anyway, when you have only 1 thread (without workers) - it's responsible for API, CLI and packet processing. But with workers - they do the packet processing. So, simultaneously you can send commands and vpp will be processing incoming packets (in case of mt-safe API call). With just one thread vpp is probably busy with API requests. Another option that you have is to configure IP settings and only then set state up.
