Hi Sasha, Since you pointed stateful PCE specifically, the draft talks about what to do during a session restart. [ https://tools.ietf.org/html/draft-ietf-pce-stateful-pce-19#section-5.6]
There is another draft that talks about optimizing it - https://datatracker.ietf.org/doc/draft-ietf-pce-stateful-sync-optimizations/ Note that we also have re-delagation, which would try to find another active stateful PCE to take over control - [https://tools.ietf.org/html/draft-ietf-pce-stateful-pce-19#section-5.7.5] As Adrian asked, do you have something else in mind when you say GR?
