Abstract
In an example, a network switch is to receive a loop detect packet from an access netwssork connected to a Data center network (DCN). The DCN includes a VXLAN overlay and the network switch is configured as a VTEP. The network switch compares the VNI of a source VTEP from which the loop detect packet originates with a locally configured VNI. In response to a match, it is determined that the network switch is configured as a peer VTEP. Import RT in the loop detect packet is compared with an export RT of the peer VTEP and the export RT in the loop detect packet is compared with an import RT of the peer VTEP. Based on the comparison, it is determined whether a VXLAN tunnel is configured between the peer and the source VTEPs. In response to the VXLAN tunnel being configured, the switch may determine that a network loop is present.
