Create an OSPF VLAN Interface

Configure the OSPF protocol on an IPv6 VLAN to support dynamic routing on the interface.

If you want to modify existing OSPFv3 interfaces, see Modify an OSPFv3 Interface.

Before you begin

  • The IPv6 interface must exist.

Procedure

  1. In the navigation pane, expand the following folders: Configuration > VLAN.
  2. Select VLANs.
  3. Select the Basic tab.
  4. Select a VLAN.
  5. Select IPv6.
  6. Select the IPv6 OSPF Interface tab.
  7. Select Insert.
  8. Select the area ID.
  9. Select enabled.
  10. Select Insert.

IPv6 OSPF Interface Field Descriptions

Use the data in the following table to use the IPv6 OSPF Interface tab.

Name

Description

Index

Shows the interface index for the IPv6 interface on which OSPFv3 is configured.

AreaId

Specifies the area ID to which the IPv6 interface connects. Use 0.0.0.0 for the OSPFv3 backbone.

Type

Specifies the OSPFv3 interface type as one of the following:

  • broadcast

  • NBMA

  • point-to-point

  • point-to-multipoint

  • passive

AdminStat

Specifies the administrative status for the OSPFv3 interface. If you enable the status, it is advertised as an interal route to some areas. If you disable the status, the interface is external to OSPFv3. The default is enabled.

RtrPriority

Specifies the priority of this interface. Multiaccess networks use the priority in the designated router election.

A higher priority value increases the chance the router becomes the designated router. A value of zero (0) indicates the router cannot become the designated router for the network. If more than one router uses the same priority value, the router ID determines the designated router.

The default is 1.

TransitDelay

Specifies the estimated number of seconds to transmit a link-state-update packet over this interface. The default is 1.

RetransInterval

Specifies the number of seconds between retransmission of link-state advertisements for the adjacencies that belong to this interface, and for database description and link-state request packets. The default is 5.

HelloInterval

Specifies the number of seconds between the hello packets that the router sends on this interface. You must configure this field to the same value for all routers attached to a common network. The default is 10.

RtrDeadInterval

Specifies the number of seconds after which to declare a router down if no hello packets are received. You must configure this field to the same value for all routers attached to a common network. The default is 40.

PollInterval

Specifies the number of seconds between hello packets sent to an inactive NBMA neighbor. The default is 120.

State

Shows the state of the OSPFv3 interface as one of the following:

  • down

  • loopback

  • waiting

  • pointToPoint

  • designatedRouter

  • backupDesginatedRouter

  • otherDesignatedRouter

DesignatedRouter

Shows the router ID for the designated router.

BackupDesignatedRouter

Shows the router ID for the backup designated router.

MetricValue

Specifies the cost for the interface. The default value for a brouter port or VLAN is 1. The default value for a tunnel is 100.

Note:

If you do not specify a cost for the interface, the switch dynamically updates the interface cost with the configured global OSPF default cost. The global OSPF default cost depends on the speed of the interface.

LinkLsaSuppression

Specifies whether Link LSA suppression is enabled.

BfdEnable

Enables Bidirectional Forwarding Detection (BFD) for OSPF.
