ABSTRACT:
Transparent point-to-point connectivity is provided between an incoming interface on an ingress node and an outgoing interface on an egress node in a network. An address associated with the egress node is circulated to the nodes in the network and a next hop address toward the egress node address is determined at each node. A label value is circulated along with the egress node address to the nodes. Examples of label values can include VLAN Ids or Multi-protocol Label Switching (MPLS) labels. If data is received having the label value, the node receiving the data identifies the next hop address associated with that label value and transfers the data to the next hop associated with the identified next hop address.
