In an embodiment, a network service provider (NSP) operates a provider network to provide VPN services to its customers. A VPN links various customer sites allowing customers to send data between these sites over the NSP network. Each site network includes a customer edge router (CE) while the provider network includes a plurality of provider edge routers (PEs) to communicate with the CEs. The PEs include virtual routing address (VRFs), and the PEs and CEs include interfaces (IFs). A database stores information related to the relationships between the network components (e.g., VPNs, PEs, CEs, VRFs, IFs, etc.), and a management software package (MSP) has access to the database. When a fault occurs, the MSP, based on collected information and information in the database, determines the impacted network components. Other features include classifying the seriousness of the network's faults and representing different faults by a color scheme.

Identifying VPN faults based on virtual routing address and edge interface relationship information

A method is disclosed for managing network nodes, such as the nodes of a network, which communicate via connectivity services of a service provider. An exemplary method includes discovering status and configuration information for each set of nodes grouped by the service provider; and assigning a name to each set of nodes.
