Create an OSPF Interface on a Tunnel
Configure the OSPF protocol on an IPv6 interface to support dynamic routing on the interface. Perform this procedure to create an OSPF interface on a tunnel.
If you want to modify existing OSPFv3 interfaces, see Modify an OSPFv3 Interface. To configure OSPFv3 on an IPv6 VLAN, see Create an OSPF VLAN Interface.
Before you begin
-
The IPv6 interface must exist.
Procedure
- In the navigation pane, expand .
- Select Tunnel.
- Select the Tunnel Config tab.
- Select a configured tunnel.
- Select IPv6 OSPF.
- Select Insert.
- Select the area ID.
- Select enabled.
- Select Insert.
OSPF Interface Field Descriptions
Use the data in the following table to use the 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 internal 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. |
