Correct Answer: C
Route leaking is the process of sharing routes between different Virtual Routing and Forwarding (VRF) instances on the same router. This can be achieved using several methods, including static routes, policy-based routing, and Border Gateway Protocol (BGP). The correct configuration involves setting up route import and export policies between the VRFs, which is typically done using route targets in BGP. The process allows for selective sharing of routes, ensuring that only the necessary routes are leaked from one VRF to another, maintaining the isolation of the remaining routes.
