Question: Would a small company with just over a hundred workers use BGP to form a WAN with two branches thirty miles and three-hundred miles from headquarters? If so, what part does BGP play?
In a job interview, where I was discussing my decade-old experience in setting up WANs using Leased T1s and my recent experience in supporting already configured MPLS, I was blanking on the acronym MPLS. The CTO interviewing me, a programmer put into the management role, said: "Well, we use BGP".
I've always understood BGP was basically the protocol that ISPs use to connect to each other through the backbone. And I didn't really need to know much about it otherwise as my IT experience has always been general IT support of smaller organizations.
After some input from the Community about what the CTO was talking about, I'll post to the IT Career group about whether and how I should follow up so that I don't look as bad I did. (My response had been, "Okay, I'll research BGP so I'm prepared to support your WAN." And in my defense, I was working on three hours sleep that day, nervous about the interview...)
