Deploying Cisco Service Provider Edge Technologies (SPEDGE, legacy) — Question 3

What is required on a Cisco IOS XR router to assign an interface to a VRF?

Answer options

• A. Assign the VRF to the interface, and then re-enable Cisco Express Forwarding on the interface.
• B. Assign the VRF to the interface, and then reset the CE-to-PE routing protocol process.
• C. Shut the interface, assign the VRF to the interface, and then no shut the interface. D.

Correct answer: C

Explanation

The correct answer is C because you must first shut down the interface to make configuration changes, then assign the VRF, and finally bring the interface back up with 'no shut'. Options A and B include steps that are not necessary for VRF assignment and would not achieve the desired configuration.
