Abstract
The use and processing of update messages (e.g., BGP UPDATEs) that bind (e.g., MPLS) labels to address prefixes is improved such that labels are used more efficiently, and/or such that such update messages can be processed more efficiently. A distance vector control signaling protocol (e.g., BGP) peer device receives a control plane message (e.g., BGP Update) from a downstream peer device, the control plane message including (1) a network address of the downstream device as a next hop value, (2) a prefix value, and (3) at least one label associated with the prefix value. Responsive to receiving the control plane message, the peer device generates a new control plane message including (1) a network address of the peer device as a next hop value, (2) the prefix value from the control plane message, and (3) a label stack including (i) the at least one label from the control plane message, and (ii) a local label associated with the peer device. The peer device then sends the new control plane message to an upstream peer device.
