[SR-Users] Dispatcher question

Hi!
I’ve used
ds_select_dst() and ds_next_dst() one after another in failure route.
If use in request/failure it’s working ok.
But again, during the failover in my environment dispatcher list can change. And I don’t want to rely on ds_next_dst() cause it can bring me absent node.
So, I’ve been thinking of use xavp variable to get data from it, but still can’t get it to work.
Regards, Igor
