Loa,

I think that Jeff means to say that " A SID instance is associated with SR-MPLS label stack. A label stack entry can be associated with a next hop. A recursive lookup may be required to derive the next hop from the topmost label stack entry."

                                                                Ron

What exactly do yo mean by "recursively"?
