Abstract

Techniques are described for supporting multiple virtual networks over an underlay network. The techniques may provide support for network slicing and enhanced virtual private networks (VPNs) over the underlay network. In general, the techniques include allocating a subset of resources (e.g., nodes and/or links) of the underlay network to a particular virtual network, and advertising the subset of resources to provider edge (PE) routers that are participating in the virtual network. A network controller device may advertise the subset of resources for the virtual network to the respective PE routers using BGP-LS (Border Gateway Protocol-Link State). Based on the advertisements, each of the PE routers generates a restricted view of the full underlay network topology for the virtual network and, thus, only uses the subset of resources in the restricted view to generate routing and forwarding tables for the virtual network.
