Devices, systems, and/or methods for monitoring IP network equipment

A method comprising:

• automatically transmitting a report to each of a plurality of provider edge routers from a central routing device of a plurality of central routing devices,
• wherein the report is indicative of a suspected failure of a provider edge router of the plurality of provider edge routers,
• wherein the central routing device automatically polls each of the plurality of provider edge routers with bidirectional forwarding detection protocol messages,
• wherein each of the plurality of provider edge routers does not communicate via interior gateway protocol messages,
• wherein the plurality of central routing devices communicate using the interior gateway protocol to disseminate routing information among the plurality of central routing devices, and
• wherein each of the plurality of provider edge routers automatically determines that the provider edge router has failed responsive to a receipt of signals from a majority of the plurality of central routing devices of the suspected failure of the provider edge router.

A system comprising:

• a processor of a central routing device of a plurality of central routing devices, wherein the processor automatically causes a transmission of a report to each of plurality of provider edge routers,
• wherein the report is indicative of a suspected failure of a provider edge router of the plurality of provider edge routers, wherein the central routing device automatically polls each of the plurality of provider edge routers with bidirectional forwarding detection protocol messages,
• wherein each of the plurality of provider edge routers does not communicate via interior gateway protocol messages, wherein the plurality of central routing devices communicate using the interior gateway protocol to disseminate routing information among the plurality of central routing devices, and
• wherein each of the plurality of provider edge routers automatically determines that the provider edge router has failed responsive to a receipt of signals from a majority of the plurality of central routing devices of the suspected failure of the provider edge router.

A non-transitory machine-readable medium comprising machine-implementable instructions for activities comprising:

• automatically determining that a second provider edge router has failed, and therefore become a suspected failure, responsive to a receipt of signals from a majority of a plurality of central routing devices of the suspected failure of the second provider edge router;
• wherein a first provider edge router and the second provider edger router are without ability to communicate via interior gateway protocol messages;
• wherein a central routing device of a plurality of central routing devices transmits a report of the suspected failure to the first provider edge router;
• wherein the central routing device polls each of the plurality of provider edge routers with bidirectional forwarding detection protocol messages, wherein the plurality of central routing devices communicate using the interior gateway protocol to disseminate routing information among the plurality of central routing devices;
• and
• at the first provider edge router of a plurality of provider edge routers, automatically changing a route of at least one forwarded packet responsive to the received report of the suspected failure of a second provider edge router of the plurality of provider edge routers which was derived from receipt of signals from the majority of the plurality of central routing devices of the suspected failure of a second provider edge router.
