    Abstract: This application discloses a route processing method and a network device. The network device obtains a route prefix and autonomous system information associated with the obtained route prefix, where the associated autonomous system information includes to-be-verified autonomous system information. The network device verifies whether there is a match item in a route origin information base, where the match item includes the obtained route prefix and the to-be-verified autonomous system information; and determines, based on a verification result, whether to send the obtained route prefix. The network device verifies the autonomous system information associated with the to-be-sent route prefix before sending the route prefix. This reduces a possibility that the network device sends route information carrying incorrect autonomous system information, and reduces a possibility of causing an abnormal network flow direction.

    Abstract: A method includes a first provider edge (PE) device sending, to a second PE device, a media access control (MAC) route learned from a customer edge (CE) device and a virtual local area network (VLAN) identifier, wherein the second PE device generates a MAC forwarding entry based on the MAC route and the VLAN identifier, where the MAC forwarding entry is used to directly forward, using the CE device, a packet whose destination MAC address is the CE device or a MAC address of a terminal device accessing the CE device. An outbound interface identifier included in the MAC forwarding entry is an identifier of an interface connected to the CE device.
