Abstract
To allow seamless interworking between an 802.1ah service instance (ISID) and a VPLS service instance, the AGI value used to signal the setup of the pseudowire portion of the VPLS may carry the ISID value of an associated 802.1ah service instance. This allows the service instance to be identified end-to-end across the Ethernet and VPLS networks using the same value without modifying how the MPLS network operates. The VPLS network will use AGI/AII signaling to set up pseudowires on the MPLS network, but instead of using an AGI value assigned by the MPLS network, the AGI value that is assigned will be taken from the ISID value of the Ethernet frame or from ISIDs registered by the Ethernet network. The AGI message may be given a new type value indicating that the AGI message carries a value that corresponds to the ISID value on an attached Ethernet network. Alternatively, an existing AGI message type may be used to carry the ISID value, and a second type field may be used to indicate that the AGI contains an ISID value.
