Exam 300-410 topic 1 question 519 discussion

D. by assigning CE-facing interfaces to different VRFs

Answer is D One wants to answer with A, but VRF-LITE has no RD, at the very least it has no route-targets (VRF-LITE = vrf without MPLS), so it can't seperate CE routes from other CE routes by using MP-BGP to propagate routes with an RD across the MPLS core.

D is corerct

I agree with D.

Kevin Wallace claims that VRF-Lite indicates the use of VRF without MPLS involved, so I'm going with D.

Agree answer is D but a poorly worded question

D is the answer

D. by assigning CE-facing interfaces to different VRFs In an MPLS (Multiprotocol Label Switching) network, Customer Edge (CE) routers are typically connected to Provider Edge (PE) routers. To keep the routes from different CE routers segregated on the PE router, Virtual Routing and Forwarding (VRF) is commonly used. Each VRF acts as a separate routing table, effectively isolating routes from one CE router from routes of another CE router. So, the correct answer is D.

The question says "on an MPLS PE router", so the question asks how to segment inside a single router.
