Layer 3 convergence for evpn link failure

A network device operable as a provider edge (PE) device of a layer 3 network, comprising:

• one or more processors operably coupled to a memory,
• wherein the one or more processors are configured to receive configuration data that configures the network device to provide, via an Ethernet segment with a customer network, active-active multi-homing layer 2 (L2) virtual bridge connectivity to the customer network using an Ethernet Virtual Private Network (EVPN) instance and layer 3 (L3) routing using an integrated routing and bridging (IRB) interface that is a L3 routing interface assigned to the EVPN instance,
• wherein the one or more processors are configured 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 address and an L3 address that are 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
• wherein the one or more processors are configured 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.

A non-transitory computer-readable medium comprising instructions for causing one or more programmable processors of a first provider edge (PE) device of a layer 3 network to:

• receive, by the first PE device, configuration data configuring the first PE device to provide, via an Ethernet segment with a customer network, active-active multi-homing layer 2 (L2) virtual bridge connectivity to the customer network using an Ethernet Virtual Private Network instance and layer 3 (L3) routing using an integrated routing and bridging (IRB) interface that is a L3 routing interface assigned to the EVPN instance;
• receive, by the first PE device from a second 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 address and an L3 address that are assigned to the customer device,
• wherein the second PE device provides, with the first PE device and via the Ethernet segment, active-active multi-homing L2 virtual bridge connectivity to the customer network;
• and
• forward, by the first PE device via the Ethernet segment and based at least on the L2-L3 binding received from the second PE device, an L3 packet to the customer device.
