Abstract
A method and a system for forwarding Ethernet packets by an Ethernet bridge in an Ethernet Layer 2 VPN network is provided. The method includes: notifying the first Ethernet bridge about the primary internal port associated with the receiving MAC-address and to the given VLAN identification; notifying the first Ethernet bridge about the backup internal port directly associated with the backup MPLS port acting as a backup MPLS port in an event of failure of the primary MPLS port; and, if the corresponding primary MPLS port has failed, forwarding Ethernet packets to the backup egress port of the receiving MAC-address having the given VLAN identification.
