This document discusses VRF (Virtual Routing and Forwarding) configuration examples on routers. It shows how to create VRF instances, associate interfaces and IP addresses, and configure routing protocols like RIP, EIGRP, OSPF and BGP to operate within VRF contexts. Specific examples demonstrated include VRF-aware static routing, and configuring BGP between VRF instances to enable inter-VRF communication. The goal is to illustrate how to segment routing tables and isolate traffic between different network segments using VRF technology.
