Basic OSPF configuration

This section provides information to configure the basic parameter for OSPF and OSPFv3 as well as configuration examples of common configuration tasks.

The minimal OSPF parameters that need to be configured are:

router ID

If a router-id is not configured in the config>router context, the router's system interface IP address is used.
one or more areas
interfaces (interface "system")

Example: Basic OSPF configuration output
