OSPF Commands

ospf
Syntax [no] ospf
Context config>service>vprn
Description
This command enables access to the context to enable an OSPF protocol instance.
When an OSPF instance is created, the protocol is enabled. To start or suspend execution of the OSPF
protocol without affecting the configuration, use the no shutdown command.
The no form of the command deletes the OSPF protocol instance removing all associated
configuration parameters.
Default
no ospf — The OSPF protocol is not enabled.
area
Syntax [no] area area-id
Context config>service>vprn>ospf
Description
This command creates the context to configure an OSPF area. An area is a collection of network
segments within an AS that have been administratively grouped together. The area ID can be
specified in dotted decimal notation or as a 32-bit decimal integer.
The no form of the command deletes the specified area from the configuration. Deleting the area also
removes the OSPF configuration of all the interfaces, virtual-links, and address-ranges etc., that are
currently assigned to this area.
Default
no area — No OSPF areas are defined.
Parameters
area-id — The OSPF area ID expressed in dotted decimal notation or as a 32-bit decimal integer.
area-range
Syntax area-range ip-prefix/mask [advertise | not-advertise]
no area-range ip-prefix/mask
Context config>service>vprn>ospf>area
ospf>service>vprn>nssa
Description
This command creates ranges of addresses on an Area Border Router (ABR) for the purpose of route
summarization or suppression. When a range is created, the range is configured to be advertised or
not advertised into other areas. Multiple range commands may be used to summarize or hide different
ranges. In the case of overlapping ranges, the most specific range command applies.
