the same link-state information is sent from multiple sources. Depending on the type of network, OSPFv3 might use a single router, thedesignated router (DR), to control the LSA floods and represent the network to the rest of the OSPFv3 area (see...
If a loopback interface exists, the router ID is the highest IP address on any active loopback interface. ? The OSPF router-id command can be used to override the OSPF router ID. ? Using a loopback interface or a router-id command is recommended for stability. Cisco Network Academy. ...

Routers send most LSAs only within one area, which reduces the CPU and memory requirements for an OSPF-enabled router. OSPFv2 supports IPv4, while OSPFv3 supports IPv6. For more information, see the "Configuring OSPFv3" chapter. Note OSPFv2 on...
ospfv3 [ process-id ] Configure the device as a stub router. stub-router [ on-startup [ interval ] ] on-startup [ interval ] specifies an interval during which a device keeps serving as a stub router after startup. By default, the interval is 500 seconds. The stub router configured ...
To prevent an OSPF route from going through a path that includes a device under upgrade or maintenance, you can configure the device as a stub router. Then, after the configuration is performed, the route on the stub router will not be selected. The link cost on the stub router is ...

On the other hand summarization is a good thing! Just not auto-summarization. On a Cisco router you have the ability to summarize particular subnets into a single larger subnet which can be used to save router resources upstream on the network such as memory and CPU cycles....
