Which command will tune the cost of the OSPF metrics for integration with non-Cisco routers to participate in OSPF?

When you're configuring Cisco routers to participate in OSPF with non-Cisco routers, each interface on the Cisco router needs to be configured. The ip ospf cost command can be tuned between 1 to 65535 and will need to be matched with the other vendor. The command ip cost 20000 is incorrect. The command ip ospf cost 20000 is also incorrect when configured in a global configuration prompt.
