- A
VRF-Lite enables multiple virtual routing tables on a single router, providing traffic separation without MPLS.
VRF-Lite creates separate routing tables per VRF, isolating traffic at Layer 3 without needing MPLS.
- B
VRF-Lite supports dynamic routing protocols such as OSPF and EIGRP within each VRF.
Dynamic routing can be configured per VRF, allowing separate routing domains to exchange routes.
- C
VRF-Lite requires MPLS to exchange VPNv4 routes between routers.
Why wrong: VRF-Lite does not use MPLS; VPNv4 route exchange requires MPLS and MP-BGP.
- D
VRF-Lite can automatically encrypt traffic between VRFs using IPsec.
Why wrong: VRF-Lite does not provide encryption; IPsec must be configured separately if needed.
- E
VRF-Lite can only be used with static routing.
Why wrong: VRF-Lite supports both static and dynamic routing protocols, not just static.
Quick Answer
The correct answer is that VRF-Lite supports dynamic routing protocols such as OSPF and EIGRP within each VRF. This is true because VRF-Lite creates multiple isolated routing tables on a single router, allowing each virtual routing and forwarding instance to run its own routing process independently, whether static or dynamic, without requiring MPLS. On the Cisco CCNP ENARSI 300-410 exam, this concept tests your understanding of how to segment traffic in an enterprise network using simple, MPLS-free VRF configurations. A common trap is assuming VRF-Lite requires MPLS or provides encryption—it does neither; it is purely a Layer 3 separation tool. Remember the memory tip: VRF-Lite is “light” because it skips MPLS, but it still runs full dynamic routing per VRF.

Correct answer & explanation
VRF-Lite enables multiple virtual routing tables on a single router, providing traffic separation without MPLS.
VRF-Lite allows multiple routing tables on a single router, enabling traffic separation without MPLS. It relies on static routes or dynamic routing protocols like OSPF, EIGRP, or BGP within each VRF. The incorrect options: MPLS is not required for VRF-Lite; VRF-Lite does not support MPLS VPNv4 route exchange (that requires MPLS); and VRF-Lite does not inherently provide encryption.
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.

Common exam traps
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Detailed technical explanation
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
- OSPF neighbours must agree on key parameters.
- Router ID selection can affect neighbour relationships and LSDB output.
- OSPF cost influences the preferred path.
- A route can appear in OSPF information but not become the installed route.
TExam Day Tips
- Check area mismatch first when OSPF adjacency fails.
- Review passive interfaces when a network is advertised but no neighbour forms.
- Use show ip ospf neighbor and show ip route clues carefully.
Key takeaway
OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Real-world example
How this comes up in practice
A network engineer at a university connects two campus buildings via a fibre link. Both routers run OSPF, but no adjacency forms — even though both routers can ping each other. The engineer finds one router is in area 0 and the other in area 1. OSPF adjacency requires matching area numbers, hello/dead timers, and network type. IP reachability alone is not enough.
What to study next
Got this wrong? Here's your next step.
Review OSPF neighbour requirements — matching area type, hello and dead timers, network type, stub flags, and authentication. Study show ip ospf neighbor states (INIT, 2-WAY, FULL). Then practise related 300-410 OSPF questions on adjacency and route selection.
