Enable BFD for OSPF on an IPv6 Port Interface

BFD for IPv6 interfaces is a demonstration feature on some products. For more information about feature support, see Fabric Engine and VOSS Feature Support Matrix.

About this task

BFD provides a failure-detection mechanism between two systems. Use the following procedure to enable BFD for the OSPF protocol on an IPv6 port interface.

Note

Note

Enabling BFD at the application level does not establish a BFD session. To establish a BFD session, you must enable BFD globally and at the interface level.

Procedure

  1. In the Device Physical View tab, select a port.
  2. In the navigation pane, expand Configuration > Edit > Port.
  3. Select IPv6.
  4. Select the IPv6 OSPF Interface tab.
  5. Select Insert.
  6. Select BfdEnable.

IPv6 OSPFv3 Interface Field Descriptions

Use the data in the following table to use the IPv6 OSPFv3 Interface tab.

Name

Description

Index

Specifies 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

Note:

Value is not configurable for OSPFv3 CLIP interfaces.

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 internal route to some areas. If you disable the status, the interface is external to OSPFv3. The default is enabled.

RtrPriority

Note:

Value is not configurable for OSPFv3 CLIP interfaces.

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

Note:

Value is not configurable for OSPFv3 CLIP interfaces.

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

RetransInterval

Note:

Value is not configurable for OSPFv3 CLIP interfaces.

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

Note:

Value is not configurable for OSPFv3 CLIP interfaces.

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

RtrDeadInterval

Note:

Value is not configurable for OSPFv3 CLIP interfaces.

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

PollInterval

Note:

Value is not configurable for OSPFv3 CLIP interfaces.

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

Note:

Value is not configurable for OSPFv3 CLIP interfaces.

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

Note:

Value is not configurable for OSPFv3 CLIP interfaces.

Specifies whether Link LSA suppression is enabled.
