Summary: | Methods and apparatuses for PW redundancy have been provided. A network node across a first domain and a second domain is disclosed. In each domain, the network node and at least one second network node form a first redundancy group (RG) in the first domain and a second RG in the second domain. The network node comprises a first set of interfaces facing the first domain, a second set of interfaces facing the second domain, and a forwarder. In the first set, at least a first and a second interfaces are configured for connecting with PW segments within the first domain; in the second set, at least a first and a second interfaces are configured for connecting with PW segments within the second domain. A third interface in the first set and a third interface in the second set are configured for transferring traffic between the network node and the at least one second network node and between the first domain and the second domain. The forwarder is configured for forwarding traffic selectively between one interface of the first set and one interface of the second set. |
