Scenario is as follows:
- bgp connection to router is up
- bgp labelled unicast (bgp-lu) route is injected through app-rib
- it is correctly advertised to router
- bgp-lu route in app-rib gets updated with change in label-stack
- change in route is reflected in app-rib adj-rib-in/effective-rib-in, but not in loc-rib and peer adj-rib-out
- updated route is not advertised to router
