Abstract

A route processing method, a device, and a system, where the method includes: a network virtualization edge (NVE) device set including at least two NVE devices includes a common Virtual Extensible Local Area Network (VXLAN) Tunnel Endpoint (VTEP) address. The common VTEP address is used to identify a common VTEP, and the common VTEP is deployed on each NVE device in the NVE device set. In addition, each NVE device in the NVE device set includes a VTEP address, and the VTEP address is used to identify a VTEP included in a corresponding NVE device. An NVE device in the NVE device set establishes a VXLAN tunnel between the NVE devices in the NVE device set based on a VTEP address and the common VTEP address using an inclusive multicast Ethernet tag (IMET) route.

Dependent claims

A route processing method applied to an Ethernet virtual private network (EVPN) comprising a first network device and a second network device, wherein the route processing method comprises:

receiving, by the first network device, a second EVPN route from the second network device, wherein the second EVPN route comprises a second common tunnel endpoint (TEP) address and a second TEP address;
and
establishing, by the first network device in response to the second common TEP address being the same as a first common TEP address stored in the first network device, a first Network Virtualization over Layer 3 (NVO3) tunnel from the first network device to the second network device based on the second TEP address in the second EVPN route.

A first network device comprising:

a non-transitory memory configured to store instructions;
and
a processor coupled to the non-transitory memory and configured to execute the instructions to cause the first network device to be configured to:
receive a second Ethernet virtual private network (EVPN) route from a second network device, wherein the second EVPN route comprises a second common tunnel endpoint (TEP) address and a second TEP address;
and
establish, in response to the second common TEP address being the same as a first common TEP address stored in the first network device, a first Network Virtualization over Layer 3 (NVO3) tunnel from the first network device to the second network device based on the second TEP address in the second EVPN route.
