Various embodiments are disclosed relating to the identification of virtual private network (VPN) topologies. In an example embodiment, a plurality of edge routers associated with a network may be discovered, each edge router including one or more virtual routing and forwarding entities (VRFs). One or more route targets (RTs) associated with each of the VRFs may be determined, wherein corresponding RTs between two or more VRFs are associated with connectivity between the two or more VRFs via the network. The VRFs may be sorted into one or more groups based upon the corresponding RTs of the VRFs. A representative VRF (rVRF) may be identified for each of the one or more groups of VRFs. The rVRFs may be sorted into one or more VPNs and a topology for each VPN may be determined.
