Title: PROVIDER EDGE DEVICE AND DATA FORWARDING METHOD
Abstract:
Provided are a provider edge device and a data forwarding method. Said method comprises: receiving a data message, the destination backbone media access control (B-MAC) address on the outer layer of data message being a B-MAC address distributed by a provider edge device to a first customer edge device; querying an Ethernet segment identifier corresponding to the B-MAC address of the first customer edge device in a forwarding table, the forwarding table comprising one-to-one correlations between a plurality of B-MAC addresses and a plurality of Ethernet segment identifiers, according to the Ethernet segment identifiers, forwarding, by means of a logical link, a de-encapsulated data message to the first customer edge device. Determining, by means of the one-to-one correlations between the B-MAC addresses and the Ethernet segment identifiers, the forwarding path for forwarding a message to the customer edge device avoids waste caused by message flow replication, achieving the effect of improving the forwarding performance of the system.
