# OSPFv3 Configuration Mode Commands

The OSPFv3 Configuration sub-mode is used to configure the OSPFv3 routing protocol. This mode includes commands that configure OSPFv3 routing parameters.

IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).

decimal_value | ipv4address

decimal_value: Specifies the identification number of the area where authentication will be enabled as an integer from 0 through 4294967295.

ipv4address: Specifies the IP address of the area where authentication will be enabled in IPv4 dotted-decimal notation.

stub [ no-summary ]

Sets the OSPFV3 stub area. Only Router-LSAs, Network-LSAs, Inter-area Prefix-LSAs, Intra-area Prefix-LSAs and Link-LSAs are allowed in a Stub area.

no-summary Does not inject inter-area routes into stub area.

virtual-link virtuallink_neighbour_Ipv4_address

Configures a virtual link to the authentication area.

virtuallink_neighbour_Ipv4_address is the IPv4 address for the virtual link of the authenticated area in dotted-decimal notation.
The following interval timers can be set for the virtual link:

- dead-interval virtuallink_dead_interval: Sets the virtual link dead-interval (in seconds) as an integer from 1 through 65535.
- hello-interval virtuallink_hello_interval: Sets the virtual link hello interval (in seconds) as an integer from 1 through 65535.
- retransmit-interval virtuallink_retransmit_interval: Sets the virtual link retransmit interval (in seconds) as an integer from 1 through 3600.
- transmit-delay virtuallink_transmit_delay: Sets the virtual link transmit delay (in seconds) as n integer from 1 through 3600.

Usage

Use this command to establish OPSFv3 areas and enable authentication.

Example

Example

The following command enables authentication for an OSPFv3 area defined by the IP address 192.168.100.10 with default cost of 256
