Hi Ron, Are you sure you get the same behavior with an interface address?
Can you please explain me how do you decapsulate and forward the inner -encapsulated- IPv6 packet on a link with a high IGP metric when the packet arrives with a DA=IPv6 interface address? Thanks, Pablo.

Why specify a USD flavor of END, END.X and END.T when you can get the exact same behavior by populating SID[0] with an IPv6 address that identifies a real interface? USD seems redundant.

USP is the default IPv6 behavior. So, if the source node specifies SID[0] as an RFC 4291 address on the SR egress node, you get the USP behavior for free. Ron Juniper Business Use Only
