M4300 Intelligent Edge Series Fully Managed Stackable Switches OSPFv3 Stub Router Commands max-metric router-lsa (OSPFv3 Router Configuration) To configure OSPFv3 to enter stub router mode, use this command in Router OSPFv3 Global Configuration mode. When OSPFv3 is in stub router mode, OSPFv3 sets the metric in the nonstub links in its router LSA to MaxLinkMetric. Other routers therefore compute very long paths through the stub router, and prefer any alternate path. Doing so eliminates all transit traffic through the stub router, when alternate routes are available. Stub router mode is useful when adding or removing a router from a network or to avoid transient routes when a router reloads. You can administratively force OSPFv3 into stub router mode. OSPFv3 remains in stub router mode until you take OSPFv3 out of stub router mode. Alternatively, you can configure OSPF to start in stub router mode for a configurable period of time after the router boots up. If you set the summary LSA metric to 16,777,215, other routers skip the summary LSA when they compute routes. If you have configured the router to enter stub router mode on startup (max-metric router-lsa on-startup), and then enter max-metric router lsa, there is no change. If OSPFv3 is administratively in stub router mode (the max-metric router-lsa command has been given), and you configure OSPFv3 to enter stub router mode on startup (max-metric router-lsa on-startup), OSPFv3 exits stub router mode (assuming the startup period has expired) and the configuration is updated. Without any parameters, stub router mode only sends maximum metric values for router LSAs. Default Format Mode OSPF is not in stub router mode by default max-metric router-lsa [on-startup seconds] [summary-lsa {metric}] max-metric router-lsa [external-lsa [max-metric-value]] [inter-area-lsas [max-metric-value]] [on-startup seconds] [summary-lsa [max-metric-value]] OSPFv3 Router Configuration Parameter external-lsa inter-area-lsas on-startup summary-lsa Description (Optional) Sends the maximum metric values for external LSAs. max-metric-value is the maximum metric value to use for LSAs. The range is 1 to 16777215 (0xFFFFFF). The default value is 16711680 (0xFF0000). (Optional) Sends the maximum metric values for Inter-Area-Router LSAs. max-metric-value is the maximum metric value to use for LSAs. The range is 1 to 16777215 (0xFFFFFF). The default value is 16711680 (0xFF0000). (Optional) Starts OSPF in stub router mode. seconds is the number of seconds that OSPF remains in stub router mode after a reboot. The range is 5 to 86,400 seconds. There is no default value. (Optional) Sends the maximum metric values for Summary LSAs. max-metric-value is the maximum metric value to use for LSAs. The range is 1 to 16777215 (0xFFFFFF). The default value is 16711680 (0xFF0000). IPv6 Commands 883 CLI Command Reference Manual
