Title: EVPN PACKET PROCESSING METHOD, DEVICE AND SYSTEM
Abstract:
An EVPN packet processing method, wherein a CE device accesses a first PE device and a second PE device in a multi-homing manner. The method comprises: the first PE device sends MAC routing and a VLAN identifier learned from the CE device to the second PE device, and the second PE device generates a MAC forwarding table item according to the MAC routing and the VLAN identifier, the MAC forwarding table item being used for directly forwarding, via the CE device, a packet for which a target MAC address is a MAC address of the CE device or a terminal device accessing the CE device. An outbound interface identifier included in the MAC forwarding table item is an identifier of an interface for connecting the CE device. The method enables the first PE device and the second PE device to form an effective load sharing for the reasonable utilisation of system bandwidth resources.
