Abstract
An E-Tree is disclosed which includes a root node associated with a Metro Ethernet network. The E-Tree includes a first Virtual Bridge (VB), associated with the root node, which is configured to process Ethernet traffic, and a second node associated with the Metro Ethernet network. The E-Tree includes a second VB, associated with the second node, configured to process Ethernet traffic and having a first connection between the first VB and the second VB. The second VB is configured to be able to send Ethernet traffic to the first VB via the first connection, if appropriate. In the event there is a second connection between the second VB and a third VB and the second connection has been assigned a down direction from the point of view of the second VB, the second VB is not permitted to send traffic received from the second connection to another connection which from the point of view of the second VB has been assigned a down direction.
