This command configures the graceful restart behavior the router.
| none | Disable graceful restart. |
| planned | Support planned restart only. |
| unplanned | Support unplanned restart only. |
| both | Support both planned and unplanned restart. |
Graceful restart is disabled by default.
When configured for planned restarts, it will support planned restarts (like process restart) and advertise Grace LSAs before restarting. When configured for unplanned restarts, it will support unplanned restarts (like failover in a stack) and advertise Grace LSAs after restarting but before sending any Hellos. When configured for both, the router will support both planned and unplanned restarts. Unplanned restarts and BFD configuration on interfaces are incompatible in ExtremeXOS. If both are enabled, an unplanned restart will fail.
This command was first available in ExtremeXOS 21.1.
This command is available on the Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X440-G2, X620, X690, X870 series switches.
