Abstract
In general, techniques are described for configuring a provider edge (PE) network device of an Ethernet virtual private network (EVPN) to use a common traffic engineering label (e.g., MPLS label) for different EVPN route types associated with the same EVPN. In some examples, the techniques include sending a first layer three (L3) control plane message that indicates a label-switched network protocol label that corresponds to a first EVPN route type, wherein the first L3 control plane message indicates that a first PE network device is reachable in the L2 segment. The techniques may include performing L2 address learning to determine at least one L2 address associated with the layer two segment of the EVPN. The techniques may include sending a second L3 control plane message that indicates the same label included in the first L3 control plane message corresponds to a second EVPN route type.
