Where would you expect to find a P router in a service provider's network?

Show Suggested Answer Hide Answer
Suggested Answer: C

A P router (Provider router) is located in the core of the service provider's network. Its functions include:

Forwarding MPLS-labeled packets between PE routers.

Not interacting directly with customer routes or routing instances.

Having no knowledge of VPN routing or customer-specific services.

Option C is correct -- P routers sit in the MPLS core, isolated from customer edge.

Definitely not A or B, those are for edge routers.

I think I saw a practice question about this, and it pointed towards the core being the right answer, but I could be wrong.

I feel like I might confuse P routers with edge routers sometimes. I hope I remember the right placement during the exam!

I remember studying that P routers handle traffic between different networks, so option C makes sense to me.

I think a P router is more likely to be in the core of the provider's network, but I'm not completely sure.
