Hi Label distribution can be done either in DOD or DU mode. It depends on the requirement. For eg. in case of L2 VPN (Martini) VCs are established using DU moode. DOD is not preferred in this case. Whenever VCID (L2 FEC) is configured, LSR sends a label mapping message to its peer. Since L2 FEC is not a part of routing information (neither destination address nor prefix) DOD is not useful. This is the one tipical example where Du is preferred.

I would like to know the actual deployment on the core. Are there any application of DU mode currently being deployed? Does any ISP is establishing LSP using DU mode of LDP? Most prominent applications of MPLS are VPN and TE. For TE you need to have CR-LSP (i.e. DOD). For VPN also Whenever you learn new PE router(by CLI or any other means) You can establish DOD LSP between the PE router. If only these are the two applications when exactly DU is configured???
