Network Segmentation: Virtual Routing Implementation

Virtual routing and forwarding (VRF) concepts have been around for a number of years, primarily directed at major ISPs for providing dedicated network connectivity for various clients over a diverse geographical area using a common underlying infrastructure. Similar implementations on campus can be used to provide "isolated networks" for specific applications (guest access, PCI, control systems, surveillance video, residential networks, affiliate organizations, etc.) that have outgrown the traditional "dedicated VLAN" separation. This presentation will show UTC's transition from a traditional flat network, to routed VLANs, to the current multiple VRF configuration.
