Route leaking between VRFs using BGP.

This article further continues on earlier experiments. While using internal tunnels gave a logically ‘simple’ point-to-point network seen from a layer 3 point of view, it came with the drawback of complex header calculations, resulting in CPU hogging on devices capable of hardware switching. Using some route-maps to choose VRFs for flows proved interesting, but […]
