32.9. OSPF Ranges table

32.9. OSPF Ranges table
	Chapter 32. OSPF - Open Shortest Path First

The table of OSPF Ranges holds information about area's ranges. The routing information is condensed at area boundaries. External to the area, at most a single route is advertised (via a summary link advertisement) for each address range. The route is advertised if and only if the address range's Status is set to Advertise. Unadvertised ranges allow the existence of certain networks to be intentionally hidden from other areas.

The table of OSPF Ranges can hold up to 100 definitions.

Commands for managing the table of OSPF Ranges are the following:

32.9.1. D OSPF RANGE

This command displays all configured OSPF ranges:

[16:53:30] ABILIS_CPX:d ospf range

- Not Saved (SAVE CONF), Not Refreshed (INIT) ---------------------------------
---------------------------------------------------------
AREA:               RANGE:                ADV:
---------------------------------------------------------
001.001.001.001     001.001.001.001/32    YES
                    001.002.002.002/32    NO 
---------------------------------------------------------
001.001.001.002     002.001.001.002/32    YES
---------------------------------------------------------

Meaning of the parameters:

AREA: This is a 32-bit number (Area ID) that identifies the owner area.
RANGE: This parameter corresponds to the range IP address and the mask in Slash Notation (i.e. x.x.x.x/yy). Doing the "logical AND" between the network IP address and the related network mask, the result should be the network itself. Networks and hosts are assigned to an area depending on whether their addresses fall into one of the area's defining address ranges. Routers are viewed as belonging to multiple areas, depending on their attached networks' area membership.
ADV: Advertise flag. The routing information is condensed at area boundaries. External to the area, at most a single route is advertised (via a summary link advertisement) for each address range. The route is advertised if and only if the address range's Status is set to Advertise. Unadvertised ranges allow the existence of certain networks to be intentionally hidden from other areas. Status is set to Advertise (1) by default.

32.9.2. A OSPF RANGE

This command defines a new OSPF range, identified by the specified mandatory parameters. The command also sets the eventually indicated optional parameters to the specified values.

[16:56:59] ABILIS_CPX:a ospf range:2.1.1.1/32 area:1.1.1.2 adv:no

COMMAND EXECUTED 

[16:57:14] ABILIS_CPX:d ospf range

---------------------------------------------------------
AREA:               RANGE:                ADV:

001.001.001.001     001.001.001.001/32    YES
                    001.002.002.002/32    NO 
---------------------------------------------------------
001.001.001.002     002.001.001.001/32    NO 
                    002.001.001.002/32    YES
---------------------------------------------------------

32.9.3. C OSPF RANGE

This command deletes an OSPF range, identified by the specified mandatory parameters.

[16:58:04] ABILIS_CPX:c ospf range:2.1.1.1/32  area:1.1.1.2

COMMAND EXECUTED 

[16:58:22] ABILIS_CPX:d ospf range

---------------------------------------------------------
AREA:               RANGE:                ADV:

001.001.001.002     002.001.001.002/32    YES
---------------------------------------------------------

32.9.4. S OSPF RANGE

This command displays a specific OSPF range, identified by the specified mandatory parameters.

[16:59:47] ABILIS_CPX:s ospf range:1.2.2.2/32 area:1.1.1.1 adv:yes

COMMAND EXECUTED 

[16:59:49] ABILIS_CPX:d ospf range
