The Lazy Man's Guide to Virtual Routing and Forwarding

Time 09/28/16 01:30PM-01:50PM

Room Trianon

Session Abstract

Virtual Routing and Forwarding (VRF) allows multiple sandboxed routing tables to be maintained on a single physical routing infrastructure.

The author has found himself baffled by the confused and incomplete accounts presented in the textbooks of how VRF operates. We object to the perception of VRF as a technology purely for Service providers. This talk will demonstrate how a 'VRF-Lite' approach can provide campus networks with a streamlined routing solution that offers substantial security benefits.

A realistic example of a segregated campus network will demonstrate how the functions performed by the Route Distinguisher and the Route Target and how routes can be carefully leaked between virtual routing tables to build a secure and centralized routing service across a campus.

Some familiarity with BGP will be assumed in this talk, but we will not dwell much on MPLS nor the associated label distribution protocols.
