display rm ipv6 bfd-session

Function

The display rm ipv6 bfd-session command displays the configurations of BFD sessions in Route Management (RM). The configurations include the global status of BFD, number of BFD sessions, and VPN instance, destination address, source address, interface, and session status of each BFD session.

Format

display rm ipv6 bfd-session [ all | [ [ vpn-instance vpn-instance-name ] [ destination destination-address ] [ source source-address ] [ interface interface-type interface-number ] [ protocol { bgp | ospfv3 } ] ] ]

Parameters

Parameter	Description	Value
vpn-instance vpn-instance-name	Specifies the name of a VPN instance.	It is case-sensitive.
destination destination-address	Specifies the remote destination address.	-
source source-address	Specifies the local source address.	-
interface interface-type interface-number	Specifies the type and number of an outbound interface.	-
protocol	Indicates a routing protocol. bgp: indicates the Border Gateway Protocol (BGP). ospfv3: indicates the Open Shortest Path First (OSPF) version 3 protocol.	-
all	Displays all the configurations of BFD sessions in RM, including the BFD sessions of the public network and VPN. If all is not specified, only the configurations of BFD sessions in the public network are displayed.	-

Default Level

1: Monitoring level

Usage Guidelines

You can use the command to view the BFD sessions that are dynamically created by the routing protocol. To modify the parameters of a BFD session, refer to the bfd all-interfaces, ospfv3 bfd, and peer bfd commands.

Example

# Display the configurations of BFD sessions in RM.

**Table 1** Description of the **display rm ipv6 bfd-session** command output
Item	Description
BFD Global Status	Global status of BFD: On: indicates that BFD is enabled globally. Off: indicates that BFD is disabled globally.
RM IPv6 BFD Session Total Number	Total number of BFD sessions
Destination	Destination IP address bound to the BFD session
Source	Source IP address bound to the BFD session
Session-State	Current status of a BFD session: AdmDown: If the shutdown (BFD session view) command is used, the BFD session enters the AdmDown state. Down: the BFD session is in the Down state. Init: the BFD session is in the Init state. Up: the BFD session is in the Up state.
Local-Discr	Local discriminator of the BFD session If the value is 0, it indicates that the RM is notified of the need to set up of a BFD session, but the RM has not instructed BFD to set up the session. If the value is not 0, it indicates that RM has instructed BFD to set up a BFD session. If you need to learn the establishment of the BFD session, you can view the Session-State.
Interface	Local physical interface bound to the BFD session
Route-Protocol	Routing protocol enabled with BFD: BGP OSPFv3
Rx-Interval (ms)	Configured receiving interval in milliseconds
Tx-Interval (ms)	Configured sending interval in milliseconds
Multiplier	Configured local detection multiplier
BFD Session Matched	Number of the BFD sessions that meet the condition
