Purpose
Enter global configuration mode.
Enable OSPF routing, and enter router configuration mode.
(Optional) Specify an address and IP subnet mask for redistributed
routes so that only one summary route is advertised.
(Optional) Establish a virtual link and set its parameters. See the
"Configuring OSPF Interfaces" section on page 38-30
definitions and Table 38-5 on page 38-27
(Optional) Force the ASBR to generate a default route into the OSPF
routing domain. Parameters are all optional.
(Optional) Configure DNS name lookup. The default is disabled.
(Optional) Specify an address range for which a single route will be
advertised. Use this command only with area border routers.
(Optional) Change the OSPF distance values. The default distance
for each type of route is 110. The range is 1 to 255.
(Optional) Suppress the sending of hello packets through the
specified interface.
(Optional) Configure route calculation timers.
• spf-delay—Delay between receiving a change to SPF
calculation. The range is from 1 to 600000. miliseconds.
• spf-holdtime—Delay between first and second SPF calculation.
The range is form 1 to 600000 in milliseconds.
• spf-wait—Maximum wait time in milliseconds for SPF
calculations. The range is from 1 to 600000 in milliseconds.
(Optional) Send syslog message when a neighbor state changes.
Return to privileged EXEC mode.

(Optional) Save your entries in the configuration file.
