Abstract
Methods, apparatus, and products are disclosed for routing frames in a TRILL network using service VLAN identifiers by: receiving a frame from an ingress bridge node for transmission through the TRILL network to a destination node that connects to the TRILL network through an egress node, the received frame including a customer VLAN identifier, a service VLAN identifier uniquely assigned to the ingress bridge node, and a destination node address for the destination node, the received frame not having mac-in-mac encapsulation; adding, in dependence upon the service VLAN identifier and the destination node address, a TRILL header conforming to the TRILL protocol, the TRILL header including an ingress bridge nickname and an egress bridge nickname; and routing, to the egress bridge node through which the destination node connects to the network, the frame in dependence upon the ingress bridge nickname and the egress bridge nickname.
