Usage guidelines
Setting the SA bit prevents neighbors from advertising the adjacency with the GR restarter when the forwarding table is not usable on the restarter. This prevents route blackholes by temporarily excluding the restarter from the SPF calculation on other RBs. If fast restart is required, you can suppress the SA bit.
