Abstract

Two or more virtual circuit (VC) labels associated with a tunnel label are mapped to a group identification (GID). The tunnel label is mapped to the GID in a GID table. When the two or more VC labels are to be associated with a new tunnel label, the tunnel label in the GID table is changed to the new tunnel label.
