Abstract
An example method is provided and may include multicasting a discovery packet in an overlay network, which includes a Layer 2 scheme over a Layer 3 network; and identifying endpoints based on their respective responses to the discovery packet, where the endpoints are coupled across a multicast backbone. In more specific embodiments, the method may include identifying disconnected endpoints in the overlay network based on a lack of responses from the disconnected endpoints.
Claims20
A method, comprising:
- multicasting a discovery packet in an overlay network to endpoints coupled across a multicast backbone, wherein each endpoint comprises a virtual Ethernet Module (VEM) and can be associated with more than one segment of the overlay network, which includes a Layer 2 scheme over a Layer 3 network, each segment being identified by a unique segment identifier (ID), wherein the discovery packet comprises a link layer multicast discovery packet configured to discover endpoints in specific segments;
- and
- identifying the endpoints based on their respective responses to the discovery packet.
Non-transitory machine-readable media encoding logic that includes instructions for execution, which when executed by a processor is operable to perform operations, comprising:
- multicasting a discovery packet in an overlay network to endpoints coupled across a multicast backbone, wherein each endpoint comprises a virtual Ethernet Module (VEM) and can be associated with more than one segment of the overlay network, which includes a Layer 2 scheme over a Layer 3 network, each segment being identified by a unique segment identifier (ID), wherein the discovery packet comprises a link layer multicast discovery packet comprises a link layer packet configured to discover endpoints in specific segments;
- and
- identifying the endpoints based on their respective responses to the discovery packet.
An apparatus, comprising:
- a debug engine;
- a memory for storing instructions;
- and
- a processor operable to execute the instructions such that the apparatus is configured for:
- multicasting a discovery packet in an overlay network to endpoints coupled across a multicast backbone, wherein each endpoint comprises a virtual Ethernet Module (VEM) and can be associated with more than one segment of the overlay network, which includes a Layer 2 scheme over a Layer 3 network, each segment being identified by a unique segment identifier (ID), wherein the discovery packet comprises a link layer multicast discovery packet comprises a link layer packet configured to discover endpoints in specific segments;
- and
- identifying the endpoints based on their respective responses to the discovery packet.
