Abstract

See full text

Systems, methods, and computer-readable storage media for detecting network loops. A system can identify, for each virtual tunnel endpoint (VTEP) from multiple VTEPs in a network, respective media access control address data including the respective local interface media access control addresses of the respective VTEP and respective media access control addresses learned by the respective VTEP. The system can determine whether the VTEPs are running spanning tree protocol (STP), and whether a media access control address learned by a first VTEP matches a respective local interface media access control address of a second VTEP. The system can detect a loop when the media access control address learned by the first VTEP matches the respective local interface media access control address of the second VTEP. The system can also detect a loop when the VTEPs are running STP and the first and second VTEPs see the same STP root bridge.
