The sender fills an authentication key into the VRRP packet, and the receiver compares the received authentication key with its local authentication key. If the two authentication keys are the same, the received VRRP packet is legitimate. Otherwise, the received packet is illegitimate. • md5—MD5 authentication.

Predefined user roles network-admin mdc-admin Parameters virtual-router-id: Specifies an IPv4 VRRP group by its virtual router ID in the range of 1 to 255. delay delay-value: Specifies a preemption delay time in the range of 0 to 255 in seconds. The default setting is 0 seconds. Usage guidelines In non-preemptive mode, when a device in the IPv4 VRRP group becomes the master, it acts as the master as long as it operates correctly, even if a backup is assigned a higher priority later.
Parameters virtual-router-id: Specifies an IPv4 VRRP group by its virtual router ID in the range of 1 to 255. priority-value: Specifies a priority value in the range of 1 to 254. A higher number indicates a higher priority. Usage guidelines VRRP determines the role (master or backup) of each device in a VRRP group by priority. A device with a higher priority is more likely to become the master. VRRP priority is in the range of 0 to 255, and a greater number represents a higher priority.

vrrp vrid track Use vrrp vrid track to associate a VRRP group with a track entry and control master switchover in the VRRP group in response to changes (such as uplink state changes) detected by the track entry. Use undo vrrp vrid track to remove the association between a VRRP group and a track entry. If no track entry is specified, the association between the VRRP group and any track entry is removed.

BFD commands The term "interface" in this chapter collectively refers to VLAN interfaces and Layer 3 Ethernet interfaces. You can set an Ethernet port as a Layer 3 interface by using the port link-mode route command (see Layer 2—LAN Switching Configuration Guide). bfd authentication-mode Use bfd authentication-mode to configure the BFD authentication mode for single-hop BFD control packets. Use undo bfd authentication-mode to restore the default.
[Sysname-Vlan-interface11] bfd authentication-mode simple 1 plain 123456 bfd demand enable Use bfd demand enable to enable the Demand BFD session mode. Use undo bfd demand enable to restore the default. Syntax bfd demand enable undo bfd demand enable Default The BFD session is in Asynchronous mode. Views Interface view Predefined user roles network-admin mdc-admin Usage guidelines In demand mode, no BFD control packets are exchanged after the session is established.
Views Interface view Predefined user roles network-admin mdc-admin Parameters value: Specifies a single-hop detection time multiplier in the range of 3 to 50. Usage guidelines The detection time multiplier determines the maximum number of concurrent BFD packets (including control packets and echo packets) that can be discarded.
Usage guidelines If you enable the echo packet mode for a BFD session in which control packets are sent and the session comes up, BFD does the following: • Periodically sends echo packets to detect link connectivity. • Decreases the control packet receiving rate at the same time. Examples # Enable the echo packet mode on VLAN-interface 11.
Syntax bfd echo-source-ipv6 ipv6-address undo bfd echo-source-ipv6 Default No source IPv6 address is configured for BFD echo packets. Views System view Predefined user roles network-admin mdc-admin Parameters ipv6-address: Specifies the source IPv6 address for BFD echo packets. Usage guidelines The source IPv6 address of echo packets can only be a global unicast address. The source IPv6 address cannot be on the same network segment as any local interface's IP address.
Usage guidelines This command sets the BFD echo packet receiving interval, which is the actual BFD echo packet sending interval. Examples # Configure the minimum interval for receiving BFD echo packets on VLAN-interface 11 as 500 milliseconds. system-view [Sysname] interface vlan-interface 11 [Sysname-Vlan-interface11] bfd min-echo-receive-interval 500 bfd min-receive-interval Use bfd min-receive-interval to configure the minimum interval for receiving single-hop BFD control packets.
bfd min-transmit-interval Use bfd min-transmit-interval to configure the minimum interval for transmitting single-hop BFD control packets. Use undo bfd min-transmit-interval to restore the default. Syntax bfd min-transmit-interval value undo bfd min-transmit-interval Default The minimum interval for transmitting single-hop BFD control packets is 400 milliseconds.
Views System view Predefined user roles network-admin mdc-admin Parameters simple: Specifies the simple authentication mode. key-id: Sets the authentication key ID in the range of 1 to 255. cipher: Sets a ciphertext password. cipher-string: Sets the ciphertext password, which is a case-sensitive string of 33 to 53 characters. plain: Sets a plaintext password. plain-string: Sets the plaintext password, which is a case-sensitive string of 1 to 16 characters.
Parameters port-number: Specifies the destination port number of multi-hop BFD control packets, 3784 or 4784. Examples # Configure the destination port number for multi-hop BFD control packets as 3784. system-view [Sysname] bfd multi-hop destination-port 3784 bfd multi-hop detect-multiplier Use bfd multi-hop detect-multiplier to configure the multi-hop detection time multiplier. Use undo bfd multi-hop detect-multiplier to restore the default.
bfd multi-hop min-receive-interval Use bfd multi-hop min-receive-interval to configure the minimum interval for receiving multi-hop BFD control packets. Use undo bfd multi-hop min-receive-interval to restore the default. Syntax bfd multi-hop min-receive-interval value undo bfd multi-hop min-receive-interval Default The minimum interval for receiving multi-hop BFD control packets is 400 milliseconds.
Predefined user roles network-admin mdc-admin Parameters value: Specifies the minimum interval for transmitting multi-hop BFD control packets, in milliseconds. The value range for this argument is 100 to 1000. Usage guidelines Use this command to make sure that the BFD packet sending rate does not exceed the device capability.

positive positive-time: Specifies the amount of time the Track module waits before notifying the application modules that the state of the track entry has changed to Positive. The positive-time argument represents the delay time in the range of 1 to 300 seconds. Usage guidelines After a track entry is created, you can only use the track nqa delay command to modify its notification delay settings. To modify other settings, you must delete the entry and create a new one.
positive positive-time: Specifies the amount of time the Track module waits before notifying the application modules that the state of the track entry has changed to Positive. The positive-time argument represents the delay time in the range of 1 to 300 seconds. Usage guidelines When you create a track entry that is associated with the link state of a specific interface, the state of the track entry is Positive if the link state of the interface is up.
ipv6: Monitors the IPv6 protocol state. When the IPv6 protocol state of an interface is up, the state of the track object is Positive. When the IPv6 protocol state of an interface is down, the state of the track object is Negative. To display the IPv6 protocol state of an interface, use the display ipv6 interface brief command. delay: Specifies the amount of time the Track module waits before notifying the application modules that the track entry state has changed.
