On which two devices are VRFs usually configured? (Choose two.)
- CE router
- Internal router
- Backbone router
- PE router
- P router
Explanation: In an MPLS L3 VPN, PE routers use VRFs to maintain separate routing tables for different customers, ensuring traffic isolation. Additionally, with the VRF-Lite feature, CE routers (customer edge devices) can also be configured with VRFs to support multiple routing domains on a single device.
