Configuring TRILL GR
Graceful Restart (GR) ensures the continuity of packet forwarding when a protocol restarts or an
active/standby switchover occurs. The device on which a protocol restarts or an active/standby
switchover occurs advertises the restart status to the neighbors, and allows the neighbors to re-establish
connections. GR involves the following roles:
• GR restarter—Graceful restarting router. It must be GR capable.
• GR helper—A neighbor of the GR restarter. It helps the GR restarter to complete the GR process.
