Usage guidelines
Setting the SA bit prevents the neighbor from advertising the ISIS-SPB adjacency with the GR restarter. This command prevents route blackholes by temporarily excluding the restarter from the SPF computation on other SPBM nodes.
Examples
# Enable ISIS-SPB to set the SA bit during a GR process.
