Abstract
A UMR auto-discovery mechanism which allows a gateway EVPN router to advertise a UMR route and to suppress redistribution of remote domain MAC-IP routes. In one embodiment, upon joining a local EVPN domain of a network, a network device (an EVPN router) advertises its UMR capability, which may include UMR installer capability or UMR originator capability. The UMR-capable devices in the network are also advertised to the newly added network device. A UMR originator (e.g., gateway) with knowledge of the UMR capabilities of the devices in the network then generates and sends a route list to the devices, where the route list includes a UMR route, or MAC/IP routes, or both, depending upon whether all of the network devices are all UMR-capable, none are UMR-capable, or the devices include both UMR-capable and non-UMR-capable devices, respectively.
