Dear All,

Can some one tell me where and how DU mode of LDP is useful?
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???


Thanks and Regards,
Prabhu
