Abstract:
A network device is configured to provide, via an Ethernet segment with a customer network, active-active multi-homing L2 virtual bridge connectivity to the customer network using an EVPN instance (EVI) and L3 routing using an IRB interface that is a L3 routing interface assigned to the EVI; to receive, from a peer PE device of the EVPN instance, an EVPN route comprising an L2-L3 binding for a customer device of the customer network and associating the L2-L3 binding with the Ethernet segment, the L2-L3 binding comprising an L2 and an L3 address assigned to the customer device, wherein the peer PE device provides, with the network device and via the Ethernet segment, active-active multi-homing L2 virtual bridge connectivity to the customer network; and to forward, via the Ethernet segment and based at least on the L2-L3 binding received from the peer PE device, an L3 packet to the customer device.
