display rm bfd-session

Function

The display rm 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 bfd-session [ all | [ [ vpn-instance vpn-instance-name ] [ destination destination-address ] [ source source-address ] [ interface interface-type interface-number ] [ protocol { bgp | isis-l1 | isis-l2 | isis-l1l2 | ospf | rip | pim } ] ] ]

Parameters

Parameter	Description	Value
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.	-
vpn-instance vpn-instance-name	Specifies the name of a VPN instance.	The value is a string of 1 to 31 case-sensitive characters, spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.
destination destination-address	Specifies the destination address.	It is in dotted decimal notation.
source source-address	Specifies the local source address.	It is in dotted decimal notation.
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. ospf: indicates the Open Shortest Path First (OSPF) protocol. rip: indicates the Routing Information Protocol (RIP). pim: indicates the Protocol Independent Multicast (PIM) protocol.	-

Usage Guidelines

You can use the display rm bfd-session command to view the BFD sessions that are dynamically created by the routing protocol.

Example

# Display the configurations of BFD sessions in RM.

<sysname> display rm bfd-session vpn-instance vrf1 destination 10.8.1.2 source 10.8.1.1 interface GigabitEthernet 0/0/10
BFD Global Status: ON
BFD Session Total Number: 1

BFD Session: 1
  Interface: GigabitEthernet 0/0/10  VRF Name: vrf1
  Destination     Source          Session-State Create-State
  10.8.1.2         10.8.1.1         Up            Established

**Table 1** Description of the **display rm 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.
BFD Session Total Number	Total number of BFD sessions
BFD Session	Number of the BFD session
Interface	Local physical interface bound to the BFD session
VRF Name	The name of a VPN instance bound to the BFD session
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.
Create-State	Set up status of a BFD session in RM: Creating: indicates that the routing protocol notifies RM of the session, but RM does not notify BFD of setting up a session. Established: indicates that RM notifies BFD of setting up a session. You can view the Session-State to check whether a BFD session is set up.
Route-Protocol	Routing protocol enabled with BFD: BGP IS-IS Level-1 IS-IS Level-2 IS-IS Level-1-2 OSPF PIM
Rx-Interval (ms)	Configured receiving interval in milliseconds
Tx-Interval (ms)	Configured sending interval in milliseconds
Multiplier	Configured local detection multiplier
BFD Session exceed The Limit number	Prompt that is displayed when the number of configured BFD sessions exceeds the upper limit
