display ospf bfd session
Format
display ospf [ process-id ] bfd session interface-type interface-number [ router-id ]
display ospf [ process-id ] bfd session { router-id | all }
Parameters
| Parameter | Description | Value |
|---|---|---|
| process-id | Specifies the ID of an OSPF process. | The value is an integer ranging from 1 to 65535. |
| interface-type interface-number | Specifies the type and number of the interface. | - |
| router-id | Specifies the router ID of the neighbor. | In dotted decimal notation. |
| all | Indicates all the OSPF-enabled interfaces in the OSPF process. | - |
Usage Guidelines
In BFD for OSPF, a BFD session is associated with OSPF. The BFD session fast detects a link fault and then notifies OSPF of the fault. This speeds up OSPF's response to the change of the network topology.
The display ospf bfd session command displays information about the BFD-enabled neighbor.
Example
# Display information about the BFD-enabled neighbor.
<AC6605> display ospf bfd session all
