I believe the WAN edge router connects to an ISP for internet access, but I can't recall if it uses a static route or dynamic routing protocols for that connection.

I'm a bit confused about the specifics. Does the WAN edge router need a separate physical connection for internet access, or can it share the MPLS link somehow?

I remember practicing a similar question about WAN architectures, and I think it might involve using a router with a dual interface for both MPLS and internet access.

I think the internet access for a WAN edge router over MPLS might involve using a dedicated internet connection, but I'm not entirely sure how that integrates with the MPLS.

I think I have a strategy for this. I'll start by considering the typical components of a WAN edge router setup, then think about how internet access is typically provided in an MPLS environment. That should help me piece together the answer.

I'm a little confused by the wording of this question. Does it mean the MPLS link is the only way the router can access the internet, or is the MPLS link just one of the options? I'll have to read it carefully.

Okay, let me see. Since the router is connected to an MPLS link, I'm guessing the internet access is likely provided through that MPLS network in some way. I'll need to review my notes on MPLS architectures.

Hmm, I'm a bit unsure about this one. I'll need to think through the details of MPLS transport links and how internet access is typically configured in that scenario.

I think I know how to approach this. I'd start by considering the different ways internet access can be provided to a WAN edge router.
