display ospfv3 bfd session

Function

The display ospfv3 bfd session command displays bidirectional forwarding detection (BFD) session information of all OSPFv3 processes.

Format

display ospfv3 [ process-id ] bfd session [ interface-name | interface-type interface-number ] [ neighbor-id ] [ verbose | all ]

Parameters

Parameter	Description	Value
process-id	Specifies the ID for an OSPFv3 process. If the process number is not specified, the information about all OSPFv3 processes is displayed in an ascending order.	The value is an integer ranges from 1 to 65535.
[ interface-name \| interface-type interface-number ]	Specifies the name, type and the number of the interface.	-
neighbor-id	Specifies router ID of the neighbor.	-
verbose	Displays detailed information of the neighbor.	-
all	Displays all the BFD sessions configured in OSPFv3.	-
