LSR Control Modes
--> LSR Control mode defines how the labels are created in the LDP enabled router.
--> LSR can create a local binding for a destination prefix in two ways:
i) Independent Control Mode
--> Each LSR creates a local label for the network which is present in the routing table.
--> Used in Cisco Devices
--> This mode causes a problem as sometimes LSR's can forward the packets before LSP is setup.
2) Ordered Control Mode
--> Each LSR creates a local label for the network only when it receives the label from next hop router.
--> Used in ATM devices.
