display pim ipv6 bfd session

Function

The display pim ipv6 bfd session command displays information about PIM IPv6 BFD sessions.

Format

display pim ipv6 bfd session [ neighbor ipv6-link-local-address | interface { interface-name | interface-type interface-number } ] ^*

Parameters

Parameter	Description	Value

Usage Guidelines

Usage Scenario

After BFD for IPv6 PIM is configured to detect the status of PIM neighbors, a PIM IPv6 BFD session needs to be established. The display pim ipv6 bfd session command can be used to view statistics about and configurations of PIM IPv6 BFD sessions.

The following commands are commonly used to view statistics and configurations of PIM IPv6 BFD sessions:

The display pim ipv6 bfd session statistics command is used to display statistics about PIM IPv6 BFD sessions in the public network instance.
The display pim ipv6 bfd session command is used to view information about PIM IPv6 BFD sessions on all interfaces of a device.
The display pim ipv6 bfd session interface interface-type interface-number neighbor neighbor-address command is used to view information about the PIM IPv6 BFD session on a specified interface or a specified neighbor.
On an IPv6 network, information about PIM-SM/SSM IPv6 BFD sessions on the public network instance can be viewed.

Example

The actual command output varies according to the device. The command output here is only an example.

# Display information about the PIM IPv6 BFD session on GE 0/1/0 in the public network instance.

<HUAWEI> display pim ipv6 bfd session interface gigabitethernet0/1/0
 VPN-Instance: public net

 GigabitEthernet0/1/0 (FE80::7): Total 1 BFD session Created

 Neighbor        ActTx(ms) ActRx(ms) ActMulti Local/Remote State
 FE80::6         100       100       4         8211/8214   Up

# Display information about PIM IPv6 BFD sessions on all interfaces of the public network instance.

<HUAWEI> display pim ipv6 bfd session
 VPN-Instance: public net
 Total 1 BFD session Created

 GigabitEthernet0/1/0 (FE80::7): Total 1 BFD session Created

**Table 1** Description of the **display pim ipv6 bfd session** command output
Item	Description
Total 1 BFD session Created	Total number of established PIM IPv6 BFD sessions.
Neighbor	IPv6 address of a PIM neighbor.
ActTx(ms)	Actual interval for sending PIM IPv6 BFD packets.
ActRx(ms)	Actual interval for receiving PIM IPv6 BFD packets.
ActMulti	Actual detection multiplier of PIM IPv6 BFD packets.
Local/Remote	Local/remote discriminator of a PIM IPv6 BFD session.
State	Status of a PIM IPv6 BFD session: Up: BFD session is set up and detection packets are exchanged periodically. Init: The local system can communicate with the peer system and the local system expects the session to go Up. Admin down: BFD session is administratively Down (the shutdown command is run in the BFD session view). Down: The BFD session is in the Down state.
VPN-Instance	VPN instance to which PIM IPv6 BFD session information belongs.
GigabitEthernet0/1/0 (FE80::7)	Name of the PIM interface (IP address).
