Rajesh, >From 8986 (section 4.16.3 last paragraph): One of the applications of the USD flavor is the case of a Topology Independent Loop-Free Alternate (TI-LFA) in P routers with encapsulation. The USD flavor allows the last SR Segment Endpoint Node in the repair path list to decapsulate the IPv6 header added at the TI-LFA Point of Local Repair and forward the inner packet.
Hope it helps. Cheers, Pablo.

Mainly USD Flavor. Apart from TILFA/MLA Decapsulation scenarios (When encapsulation is used at transit PLR). Thanks Rajesh Juniper Business Use Only
