What does this VRF routing table output indicate?
- The router is a P router in an MPLS network
- The router is configured as a PE router with VRF-Lite
- The routes are learned via OSPF
- The router is running standard BGP without VRF support
Explanation: According to the sources, VRF-Lite provides the ability to configure and maintain more than one VRF instance within the same PE router to support multiple routing domains .
A router that displays a VRF-specific routing table is functioning as a PE router because P routers in an MPLS core are unaware of VPN routes and do not maintain VRF tables .
This isolation allows a single physical device to serve multiple customers with overlapping address spaces by using separate, isolated routing and forwarding tables .
Therefore, an output generated by a command such as show ip route vrf indicates that the router is configured with VRF-Lite functionality to manage these distinct routing contexts .
