EXAMPLE
In the following example, the summary address 10.1.0.0 includes address 10.1.1.0, 10.1.2.0, 10.1.3.0, and so on. Only
the address 10.1.0.0 is advertised in an external link-state advertisement.
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
Configuring OSPF Interfaces, page 827
definitions and the Default OSPF Configuration, page 825
for virtual link defaults.
(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.
Display lists of information related to the OSPF database for
a specific router. For some of the keyword options, see
Monitoring OSPF, page 837.
(Optional) Save your entries in the configuration file.
