Abstract
Certain exemplary embodiments can provide a method that can comprise automatically rendering information indicative of a cause of a failure in a Virtual Private Network (VPN) that comprises one or more routers that utilize Virtual Routing and Forwarding (VRF) tables to route traffic via the VPN. The cause of the failure can be automatically determined.
Claims19
A method comprising:
- automatically rendering information indicative of a cause of a failure in a Virtual Private Network (VPN) that comprises at least one or more router that utilizes Virtual Routing and Forwarding (VRF) tables to route traffic via the VPN, the cause of the failure automatically determined by a rules based expert system configured to:
- automatically analyze VRF alerts comprising Multi-Protocol Label Switching (MPLS) VRF link up alerts and MPLS VRF link down alerts;
- automatically correlate VRF threshold alerts of the VRF alerts to customer edge routers;
- and
- automatically determining that a count of VRF circuits associated with a customer has exceeded a maximum threshold count of VRF circuits, the customer associated with the VPN.

A non-transitory computer-readable medium encoded with computer executable instructions for activities comprising:
- automatically rendering information indicative of a cause of a failure in a Virtual Private Network (VPN) that comprises at least one router that utilizes Virtual Routing and Forwarding (VRF) tables to route traffic via the VPN, the cause of the failure automatically determined by a rules based expert system configured to:
- automatically compare a VRF Name obtained from a router, of the at least one router, with a name in an inventory database;
- automatically check connectivity between a Customer Edge router and a Provider Edge router via a Packet Internet Groper (ping) signal transmitted over a VRF link:
- and
- automatically determining that a count of VRF circuits associated with a customer has exceeded a maximum threshold count of VRF circuits, the customer associated with the VPN.

A method comprising:
- automatically rendering information indicative of a cause of a failure in a Virtual Private Network (VPN) that comprises at least one router that utilizes Virtual Routing and Forwarding (VRF) tables to route traffic via the VPN, the cause of the failure automatically determined by a rules based expert system configured to:
- automatically check a layer three port status of the VPN;
- and
- automatically report problems related to layer one and layer two facilities of the VPN;
- and
- automatically determining that a count of VRF circuits associated with a customer has exceeded a maximum threshold count of VRF circuits, the customer associated with the VPN.

A method comprising:
- automatically rendering information indicative of a cause of a failure in a Virtual Private Network (VPN) that comprises at least one router that utilizes Virtual Routing and Forwarding (VRF) tables to route traffic via the VPN, the cause of the failure automatically determined by a rules based expert system configured to:
- automatically report a VRF configuration problem;
- and
- automatically determining that a count of VRF circuits associated with a customer has exceeded a maximum threshold count of VRF circuits, the customer associated with the VRF;
- automatically notify the customer associated with the VRF if a count of VRF circuits of the customer exceeds a maximum threshold.

- automatically analyze VRF alerts comprising Multi-Protocol Label Switching (MPLS) VRF link up alerts and MPLS VRF link down alerts;
- and
- automatically compare a VRF Name obtained from a router, of the at least one router, with a name in an inventory database;
- automatically determining that a count of VRF circuits associated with a customer has exceeded a maximum threshold count of VRF circuits, the customer associated with the VPN;
- and
- a user interface adapted configured to automatically render the information indicative of the cause of the failure.
