vrouter-ospf-area-show

This command is used to display information about areas and stubs as well as prefixes in an OSPF configuration.

Syntax   vrouter-ospf-area-show vrouter-name name-string area area-number [stub-type none|stub|stub-no-summary|nssa|nssa-no-summary] [prefix-list-in vrouter prefix-list name][prefix-list-out vrouter prefix-list name]

vrouter-name name-string

Specify the name of the vRouter.

Specify the following OSPF area arguments:

area area-number

Specify the area number.

stub-type none|stub|stub-no-summary|
nssa|nssa-no-summary

Specify the OSPF stub type.

prefix-list-in vrouter prefix-list name

Specify an inbound prefix list name.

prefix-list-out vrouter prefix-list name

Specify an outbound prefix list name.

Formatting Options

format fields-to-display

Display output using a specific parameter. Use all to display all possible output.

parsable-delim character

Display output formatted for machine parsing using a specified delimiter.

sort-asc

Display output in ascending order.

sort-desc

Display output in descending order.

show dups

Display duplicate entries in the output.

layout vertical|horizontal

Format the output in a vertical or horizontal layout.

show-interval seconds-interval

Repeat the show command at a specified interval.

show-headers|
no-show-headers

Display column headers or not.

limit-output number

Limit the display output to a specific number of entries.

count-output

Display the number of entries in the output. This is useful with vRouter show commands.

unscaled

Display full values in the output instead of scaled approximate values.

raw-int-values

Display integer values instead of mapped values

sum-by

Aggregate output by specific parameters. If sum-by fields are specified, records that have the same value in sum-by fields are combined and displayed as one aggregate record. NOTE: This option is only available for show commands that collect statistics such as connection-stats-show.

Defaults   None

Access   CLI

History   Command introduced in Version 2.2.3.

Usage   An OSPF network can be divided into sub-domains called areas. An area is a logical collection of OSPF networks, routers, and links that have the same area identification.. A router within an area must maintain a topological database for the area to which it belongs. The router doesn't have detailed information about network topology outside of its area, thereby reducing the size of its database.

Areas limit the scope of route information distribution. It is not possible to do route update filtering within an area. The link-state database (LSDB) of routers within the same area must be synchronized and be exactly the same. However, route summarization and filtering is possible between different areas. The main benefit of creating areas is a reduction in the number of routes to propagate through the filtering and the summarization of routes.

Examples  To display information about an OSPF area, use the following syntax:

CLI network-admin@switch > vrouter-ospf-area-show vrouter-name vrouter-ospf area 0 stub-type stub
