Commands For Ospfv3

8.6 Commands for OSPFv3

8.6.1 area default cost

Command: area <id> default-cost <cost>
no area <id> default-cost
Function: Configure the cost to send to the default summary route in the stub or NSSA area. The no command restores the default value.
Parameters:

  • <id>: area number. The value could be shown as digits 0 to 4294967295 or as an IP address.
  • <cost>: cost. The valid range is between 0 and 16777215.

Command mode: OSPFv3 protocol mode
Default: Default OSPFv3 cost is 1.
Usage guide: The command is only used for the ABR router connected to the stub area.
Example: Set the default-cost of area 1 to 10.

active500EM(config-router)#area 1 default-cost 10

 

8.6.2 area range

Command: area <id> range <ipv6address> [advertise| not-advertise|] no area <id> range <ipv6address>
Function:Aggregate OSPF route on the area border. The no command cancels this function.
Parameters:

  • <id>: area number. The value could be shown as digits 0 to 4294967295 or as an IP address.
  • <ipv6address>=<X:X::X:X/M>: specifies the area IPv6 network prefix and its length.
  • advertise: advertise this area.
  • not-advertise: do not advertise this area.
  • If both are not set, this area is defaulted to advertising.

Command mode: OSPFv3 Protocol Mode
Default: Function not configured.
Usage guide: Use this command to aggregate routes inside an area. If the
network IDs in this area are not configured sequentially, a summary route can be advertised by configuring this command on ABR. This route consists of all single networks belonging to a specific range.
Example: Aggregate an OSPF route on the area border.

active500EM#config terminal
active500EM(config)#router ipv6 ospf
active500EM(config-router)#area 1 range 2000::/3

 

8.6.3 area stub

Command: area <id> stub [no-summary] no area <id> stub [no-summary] Function: Define an area to a stub area. The no command cancels this function.
Parameters:

  • <id>: area number. The valid value could be digits ranging between 0 and 4294967295 or an IPv4 address.
  • no-summary: the area border routes stop sending link summary announcements to the stub area.

Command mode: OSPFv3 Protocol Mode
Default: Not defined.
Usage guide: Configure the area stub on all routes in the stub area. There are two configuration commands for the routers in the stub area: stub and default-cost. All routers connected to the stub area should be configured with the area stub command. As for area border routers connected to the stub area, the introduced cost is defined via the area default-cost command.
Example: Define an area to a stub area.

active500EM#config terminal
active500EM(config)#router ipv6 ospf
active500EM(config-router)#area 1 stub

Related Command: area default-cost
 

Command: area <id>virtual-link A.B.C.D [instance-id <instance-id>| INTERVAL <value>] no area <id>virtual-link A.B.C.D [instance-id <instance-id>| INTERVAL] Function: Configure a logical link between two backbone areas physically divided by a non-backbone area. The no command removes this virtual-link.
Parameters:

  • <id>: area number: The valid value is digits ranging between 0 and 4294967295 or an IP address.
  • <instance-id>: interface instance ID. The valid range is between 0 and 255. The default is 0.
  • INTERVAL= [dead-interval|hello-interval|retransmit-interval|transmit-delay]
  • <value>:delay or interval seconds. The valid range is between 1 and 6553.
  • <dead-interval>: a neighbor is considered offline based on a specified dead interval. The default is 40 seconds.
  • <hello-interval>: time interval before the router sends a hello group message. The default is 10 seconds.
  • <retransmit-interval>: time interval before a router retransmits a group message. The default is 5 seconds.
  • <transmit-delay>: time delay before a router sends a group messages. The default is 1 second.

Command mode: OSPFv3 Protocol Mode
Default: No default configuration.
Usage guide: In the OSPF, all non-backbone areas will be connected to a backbone area. If the connection to the backbone area is lost, virtual link will repair this connection. Virtual links can be configured between any two backbone areas routers connected with the public non-backbone area. The protocol treats routers connected by virtual links as a point-to-point network.
Example: Configure a logical link between two backbone areas physically divided by a non-backbone area.

active500EM#config terminal
active500EM(config)#router ipv6 ospf
active500EM(config-router)#area 1 virtual-link 10.10.11.50 hello 5 dead 20
active500EM(config-router)#area 1 virtual-link 10.10.11.50 instance-id 1

 

8.6.5 abr-type

Command: abr-type {cisco|ibm| standard}
no abr-type [cisco|ibm| standard] Function: Configure an OSPF ABR type with this command. The no command restores the default.

  • shortcut: specify a shortcut-ABR.
  • standard: realize with standard?RFC2328?ABR.

Command mode: OSPFv3 protocol mode
Default: Cisco configured.
Usage guide: This command specifies the realized ABR type. This command is good for interactive operation among different OSPF realized methods and is especially useful in multiple host environments.
Example: Configure ABR as standard.

active500EM#config terminal
active500EM(config)#router ipv6 ospf
active500EM(config-router)#abr-type standard

 

8.6.6 default-metric

Command: default-metric <value>
no default-metric
Function: Set the default OSPF routing protocol metric value. The no command returns to the default state.
Parameters:

  • <value>: metric value. The valid range is between 1 and 16777214.

Command mode: OSPF Protocol Mode
Default: Metric value is set to auto translate.
Usage guide: When the default metric value is incompatible, the introduced route will still go through. If the metric value can not be translated, the default value provides an alternative option to carry the introduced route. This command sets all introduced routes to the same metric value. This command should be used with the redistribute command.
Example: Set the default OSPF routing protocol metric value.

active500EM#config terminal
active500EM(config)#router ipv6 ospf
active500EM(config-router)#default-metric 100

8.6.17 ipv6 ospf dead-interval

Command: ipv6 ospf dead-interval <time >[instance-id <id>] no ipv6 ospf dead-interval [instance-id <id>] Function: Specify the dead interval for a neighboring Layer 3 switch. The no command restores the default value.
Parameters:

  • <id>: interface instance ID. The valid range is between 0 and 255. The default is 0.
  • <time>: length of the adjacent Layer 3 switch. The value is seconds and the valid range is between 1 and 65535.

Command mode: Interface Configuration Mode
Default: The default dead interval is 40 seconds (normally 4 times the hello-interval).
Usage guide: If no Hello data packet is received after the dead-interval period then the Layer 3 switch is considered inaccessible and invalid. This command modifies the neighboring Layer 3 switch dead interval value according to the actual link state. The set dead-interval value is written into the Hello packet and transmitted. To ensure normal operation of the OSPF protocol, the dead-interval between adjacent Layer 3 switches should be in accordance or at least 4 times of the hello-interval value. The command can configure a IPv6 tunnel interface.
Example: Specify the dead interval for a neighboring Layer 3 switch.

active500EM#config terminal
active500EM(config)#interface vlan 1
active500EM(Config-if-Vlan1)#ipv6 ospf dead-interval 80

 

8.6.18 ipv6 ospf display route single-line

Function: Change the display results of the ?show ipv6 ospf route? command. The no command restores to the default display mode.
Parameters: None.
Command mode: Global Mode
Default: Not configured.
Usage guide: The ?show ipv6 ospf route? command displays the same route in several lines. This command will display one route on one line.
Example: Change the display results of the ?show ipv6 ospf route? command.

active500EM#config terminal
active500EM(config)#ipv6 ospf display route single-line

 

8.6.19 ipv6 ospf hello-interval

Command: ipv6 ospf hello-interval <time>[instance-id <id>] no ipv6 ospf hello-interval [instance-id <id>] Function: Specify the hello-interval on the interface. The no command restores the default value.
Parameters:

  • <id>: interface instance ID. The valid range is between 0 and 255. The default is 0.
  • <time>: length of the adjacent layer 3 switch. The valid value is seconds with a range between 1 and 65535.

Command mode: Interface Configuration Mode
Default: Default Hello packet sending interval is 10 seconds.
Usage guide: Hello data packet is the most common packet which is periodically sent to adjacent Layer 3 switches to discover and maintain adjacent relationships (elect DR and BDR). The user sets the hello-interval value to be written into the Hello packet which is then transmitted. The lower the hello-interval value, the sooner the network topology structure is discovered and the larger the cost. To ensure the normal operation of the OSPF protocol, the hello-interval parameter between the Layer 3 switches adjacent to the interface must be relative to each other. This command can configure an IPv6 tunnel interface.
Example: Specify the hello-interval on the interface.

active500EM#config terminal
active500EM(config)#interface vlan 1
active500EM(Config-if-Vlan1)#ipv6 ospf hello-interval 20

Related Command: ipv6 ospf dead-interval
 

8.6.20 ipv6 ospf priority

Command: ipv6 ospf priority <priority> [instance-id <id>] no ipv6 ospf priority[instance-id <id>] Function: Configure the priority when electing ?Defined layer 3 switch? at the interface. The no command restores the default value.
Parameters:

  • <id>: interface instance ID. The valid range is between 0 and 255. The default is 0.
  • <priority>: priority. The valid range is between 0 and 255.

Command mode: Interface Configuration Mode
Default: The default priority when electing DR is 1.
Usage guide: When two Layer 3 switches connected to the same segments both want to be the ?Defined layer 3 switch?. The priority will determine which is chosen. Normally, the switch with the higher priority will be elected. Alternatively, the switch with the larger router-id number will be selected if the priorities of both switches are the same. A Layer 3 switch with a priority equal to 0 will not be elected as the ?Defined Layer 3 switch? or ?Backup Defined Layer 3 switch?. This command can configure a IPv6 tunnel interface.
Example: Configure the DR elect priority. Configure the interface VLAN 1 to no election right, namely set the priority to 0.

active500EM#config terminal
active500EM(config)#interface vlan 1
active500EM(Config-if-Vlan1)#ipv6 ospf priority 0

 

8.6.21 ipv6 ospf retransmit-interval

Command: ipv6 ospf retransmit-interval <time>[instance-id <id>] no ipv6 ospf retransmit-interval [instance-id <id>] Function: Specify the link state announcement retransmit interval between the interface and adjacent Layer 3 switches. The no command restores the default value.
Parameters:

  • <id>: interface instance ID. The valid range is between 0 and 255. The default is 0.
  • <time>: retransmit interval of link state announcements between the interface and adjacent Layer 3 switches. The value is shown in seconds with a range between 1 and 65535.

Command mode: Interface Configuration Mode
Default: The default retransmit interval is 5 seconds.
Usage guide: When a Layer 3 switch transmits LSA to its neighbor, it will maintain the link state announcements until a confirmation is received from the object side. If the confirmation packet is not received within the interval, the LSA will be retransmitted. The retransmit interval must be larger than the time it takes to make a round between two Layer 3 switches. The command can configure an IPv6 tunnel interface.
Example: Configure the LSA retransmit interval of interface vlan 1 to 10 seconds.

active500EM#config terminal
active500EM(config)#interface vlan 1
active500EM(Config-if-Vlan1)#ipv6 ospf retransmit-interval 10

 

8.6.22 ipv6 ospf transmit-delay

Command: ipv6 ospf transmit-delay<time>[instance-id <id>] no ipv6 ospf transmit-delay [instance-id <id>] Function: Configure the LSA sending delay time on the interface. The no command restores to the default.
Parameters:

  • <id>: instance ID. The valid range is between 0 and 255. The default is 0.
  • <time>: sending LSA delay time on the interface. The valid value is seconds with a range between 1 and 65535.

Command mode: Interface Configuration Mode
Default: The send LSA default delay time on the interface is 1 second.
Usage guide: The LSA ages over time in the layer 3 switches but not in the transmission process. By increasing the transmit-delay before sending LSA it will be sent out. The command can configure an IPv6 tunnel interface.
Example: Set the interface VLAN 1 LSA sending delay to 3 seconds.

active500EM#config terminal
active500EM(config)#interface vlan 1
active500EM(Config-if-Vlan1)#ipv6 ospf transmit-delay 3

no ipv6 router ospf {area <area-id> [instance-id <instance-id>]| tag <tag>[instance-id <instance-id>]}|tag <tag> area <area-id> [instance-id <instance-id>]}
Function: Enable an OSPF route on the interface. The no command cancels this configuration.
Parameters:

  • <area-id>: area ID. The valid value is digits ranging between 0 and 4294967295 or an IPv4 address.
  • <instance-id>: interface instance ID. The valid range is between 0 and 255. The default is 0.
  • <tag>: OSPFv3 process identifier.

Command mode: Interface Configuration Mode
Default: Not configured.
Usage guide: To enable this command on the interface the area ID must be configured. The instance ID and instance tag are optional. The OSPFv3 process allows one routing instance for each instance ID. The route can be enabled on an interface with an instance ID. If the instance IDs are different, several OSPF processes can be run on one interface. However, different OSPF processes should not use the same instance ID. The command can configure an IPv6 tunnel interface.
Example: Enable an OSPF route on the interface.

active500EM#config terminal
active500EM(config)#interface vlan 1
