SERVICE DISCOVERY ACROSS TUNNEL ENDPOINTS IN OVERLAYS

In an example, a network device may receive, from a client device, a multicast query for a service advertised by a host device connected to another network device. The network device is configured as a first Virtual tunnel endpoint (VTEP) and the other network device is configured as a second VTEP in an overlay network. The network device may determine whether a host name, of the host device, corresponding to the service name in the multicast query is present in a resource record. In response to determining that the host name is present in the resource record, the network device may identify, from the resource record, an overlay network path corresponding to the host name. The network device may encapsulate the multicast query based on an overlay encapsulation protocol implemented at the first VTEP and route, the encapsulated multicast query, via the overlay network path, to the host device.
