For Hello and dead interval:

Router (config-if) # ip ospf hello-interval seconds

Specify the length of time between the hello packets that the Cisco IOS software sends on an OSPF interface.

Router (config-if) # ip ospf dead-interval seconds

Set the number of seconds that a device's hello packets must not have been seen before its neighbors declare the OSPF router down.

For authentication:

Router (config-if) # ip ospf authentication message-digest

Router (config-if) # ip ospf message-digest-key x md5 password
