Peter, An extended link LSA can contain multiple adj-sid labels with "s bit" set. During graceful restart , when self generated LSAs are learnt from neighbors, A handle is required to associate the set label with the bundle.
I think a group-id field along with set label would serve the purpose.

That way you can create multiple sets as you need. thanks, Peter On 12/13/14 19:19 , Shraddha Hegde wrote: > Authors, > > When there are multiple parallel links between two nodes, it > is useful to > > Group them into different bundles and use each bundle for load-balancing > for different traffic flows. > > What we have in adjacency sid is just a flag to indicate that the > label is a "set label" by setting a flag > > In adj-sid TLV.
