Supported on all 7210 SAS platforms as described in this document
The config>router>ospf>segment-routing context is supported only on the 7210 SAS-Mxp, 7210 SAS-R6, 7210 SAS-R12, and 7210 SAS-Sx/S 1/10GE.
This command administratively disables the entity. When disabled, an entity does not change, reset, or remove any configuration settings or statistics. Many entities must be explicitly enabled using the no shutdown command.
Unlike other commands and parameters where the default state is not indicated in the configuration file, shutdown and no shutdown are always indicated in system generated configuration files.
The no form of this command puts an entity into the administratively enabled state.
The Open Shortest Path First (OSPF) protocol is created in the no shutdown state.
When an IP interface is configured as an OSPF interface, OSPF on the interface is in the no shutdown state by default.
On the 7210 SAS-Mxp, the protocol is handled as follows.
The configure router ospf command instantiates the protocol in the no shutdown state and resources are allocated to enable the node to process the protocol.
To deallocate resources, issue the configure router ospf shutdown and configure router no ospf commands to allow the node to boot up correctly after the reboot. It is not sufficient to only issue a configure router ospf shutdown command.
Resources for OSPF are allocated when the OSPF context is enabled either in the base routing instance or the VPRN service instance. Resources are deallocated when the configuration of the last OSPF context under either base routing instances or VPRN service is removed or shut down.
On the 7210 SAS-Mxp, the protocol is handled as follows.
The configure router ospf3 command instantiates the protocol in the no shutdown state and resources are allocated to enable the node to process the protocol.
To deallocate resources, issue the configure router ospf3 shutdown and configure router no ospf3 commands to allow the node to boot up correctly after the reboot. It is not sufficient to only issue a configure router ospf3 shutdown command.
Resources are allocated when the OSPFv3 instance is enabled and resources are deallocated when the OSPFv3 instance is removed or shut down.
