Abstract
Systems and methods provide a new type of time-length-value data stream (TLV) which can be encapsulated in an OAM ping packet. This 'EVI TLV' encapsulating OAM ping packet can be sent to a network device (e.g., a border router) that a liaison VRF is provisioned on. Upon receipt, the encapsulated EVI TLV instructs the network device to determine whether the configuration of the liaison VRF is mapped to an EVI value specified by the EVI TLV. If the configuration of the liaison VRF is mapped to the specified EVI value, the network device returns an echo response indicating that the configuration of the liaison VRF is mapped onto the specified EVI value. Such a response may indicate that the liaison VRF is reachable for the EVPN.
