GR due to topology changes. If one wants to capture topology changes
during restart yes they have to do beyond GR(NSR?).
However, in the bis document with planned restart indication this is being
introduced (i.e., exiting GR if "any" topology change is detected by the
neighbor of restating router).

Thank you!
