Parameters

Parameter	Description	Value
vpn-instance vpn-instance-name	Specifies the name of a VPN instance.	The value must be an existing VPN instance name.
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). isis-l1: indicates IS-IS Level-1. isis-l2: indicates IS-IS Level-2. Isis-l1l2: indicates IS-IS Level-1-2. ospfv3: indicates the Open Shortest Path First (OSPF) version 3 protocol. pim: indicates the Protocol Independent Multicast (PIM) 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.	-

Usage Guidelines

You can use the command to view the BFD sessions that are dynamically created by the routing protocol. 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. To modify the parameters of a BFD session, refer to the bfd all-interfaces, ospfv3 bfd, isis ipv6 bfd, and peer bfd.

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 IS-IS Level-1 IS-IS Level-2 IS-IS Level-1-2 OSPFv3 PIM
Rx-Interval (ms)	Configured receiving interval in milliseconds.
Tx-Interval (ms)	Configured sending interval in milliseconds.
Multiplier	Configured local detection multiplier.
VPN-Name	Name of the VPN instance.
