Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 329
A network engineer has set up VRF-Lite on two routers where all the interfaces are in the same VRF. At a later time, a new loopback is added to Router 1, but it cannot ping any of the existing interfaces. Which two configurations enable the local or remote router to ping the loopback from any existing interface? (Choose two.)
Answer options
- A. adding a static route for the VRF that points to the global route table
- B. adding the loopback to the VRF
- C. adding dynamic routing between the two routers and advertising the loopback
- D. adding the IP address of the loopback to the export route targets for the VRF
- E. adding a static route for the VRF that points to the loopback interface
- F. adding all interfaces to the global and VRF routing tables AB
Correct answer:
Explanation
The correct answers are B and C. Adding the loopback to the VRF (B) ensures that it is part of the same routing context, allowing for communication. Establishing dynamic routing (C) enables the loopback to be advertised to the remote router. The other options either do not address the VRF context or do not facilitate communication with the loopback.
