2V0-41.24 Question 152
Select 3A network administrator is tasked with configuring VRF Lite on a physical router in a multi-tenant environment. The goal is to isolate routing tables for different tenants while minimizing complexity. Which of the following statements correctly describes VRF Lite and its functionality?
- A
VRF Lite allows for the creation of multiple virtual routing tables on a single router.
- B
VRF Lite requires MPLS to function correctly.
- C
VRF Lite is commonly used in environments where tenants need isolated routing instances without additional hardware.
- D
VRF Lite automatically exchanges routing information between virtual routing tables without additional configuration.
- E
VRF Lite can be used to segregate traffic for different customers or departments within the same enterprise.
Show answer and explanation
Correct answers: A, C, E
Explanation
VRF Lite is a technology that enables the logical separation of routing tables on a single physical router, making it ideal for multi-tenant environments or enterprises needing traffic segregation. It does not require MPLS and does not automatically exchange routing information between VRFs, making it simpler than MPLS-based VRFs but requiring manual configuration for route leaking if necessary.
- A. Correct.
This is correct. VRF Lite enables the creation of multiple virtual routing tables on a single physical router, allowing logical separation of routing instances.
- B. Incorrect.
This is incorrect. Unlike MPLS-based VRFs, VRF Lite does not require MPLS; it is a simpler mechanism for routing table isolation.
- C. Correct.
This is correct. VRF Lite is used in multi-tenant environments to isolate routing instances without the need for additional hardware, making it cost-effective.
- D. Incorrect.
This is incorrect. VRF Lite does not automatically exchange routing information between virtual routing tables. Route leaking must be configured manually if needed.
- E. Correct.
This is correct. VRF Lite is often used to segregate traffic for different customers, tenants, or departments within a shared network infrastructure.
