Enable BFD for OSPF on an IPv6 VLAN Interface
BFD for IPv6 interfaces is a demonstration feature on some products. For more information about feature support, see VOSS Feature Support Matrix.
About this task
BFD provides a failure-detection mechanism between two systems. Use the following procedure to enable OSPF BFD on an IPv6 VLAN interface.
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
- In the navigation pane, expand the folders.
- Select VLANs.
- Select the Basic tab.
- Select the VLAN on which you want to enable BFD for OSPF.
- Select IPV6.
- Select IPv6 OSPF Interface.
- Select Insert.
- Select BfdEnable.
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:
|
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:
|
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. |
