Usage guidelines Specify the type of the MAC addresses mapped to the virtual IP address before creating a VRRP group. Otherwise, you cannot change the type of the MAC address by using this command.
Because devices from different vendors might implement VRRP in a different way, when the device is interoperating with devices of other vendors, VRRP packet TTL check might result in dropping packets that should not be dropped. In this situation, use the vrrp un-check ttl command to disable TTL check on VRRP packets. Examples # Disable TTL check on VRRP packets.
You might configure different authentication modes and authentication keys for the VRRP groups on an interface. However, the members of the same VRRP group must use the same authentication mode and authentication key. Examples # Set the authentication mode to simple and authentication key to Sysname for VRRP group 1 on interface GigabitEthernet 1/0/1 to send and receive VRRP packets. system-view [Sysname] interface gigabitethernet 1/0/1 [Sysname-GigabitEthernet1/0/1] vrrp vrid 1 virtual-ip 10.1.
A VRRP group member might need some time to back up ARP entries before it becomes the new master. To reserve enough ARP entry backup time, configure a proper preemption delay for the VRRP group based on the number of ARP entries. Examples # Enable ARP entry backup on GigabitEthernet 3/0/1 for IPv4 VRRP group 1. system-view [Sysname] interface gigabitethernet 3/0/1 [Sysname-GigabitEthernet3/0/1] vrrp vrid 1 virtual-ip 10.1.1.

The Layer 2 protocol used by the tracked synchronous/asynchronous serial interfaces can be PPP only, and the tracked synchronous/asynchronous serial interfaces cannot be added to a virtual template or MP-group; the dialer interface should function as the PPPoE client and operate in the permanent online mode; the BRI interface should operate in the dedicated line mode.
or the configured IP address is the network address or network broadcast address of the network segment to which the interface IP address belongs, though you can perform the configuration successfully, the state of the VRRP group is always Initialize, which means VRRP does not take effect . Examples # Create VRRP group 1 and set its virtual IP address to 10.10.10.10. system-view [Sysname] interface gigabitethernet 1/0/1 [Sysname-GigabitEthernet1/0/1] vrrp vrid 1 virtual-ip 10.10.10.
If the track entry specified in this command does not exist, you can use the vrrp vrid weight track command to specify a track entry, and then create the track entry using the track command. The weight of a VF is 255, and the lower limit of failure is 10. When the weight of a VF owner is no less than the lower limit of failure, the priority of the VF owner is always 255.

If no interface is specified, the undo vrrp ipv6 vrid track interface command removes the association between the VRRP group and any interface. If you configure an interface to be tracked on a router that is the IP address owner in a VRRP group, the configuration does not take effect. If the router is not the IP address owner in the VRRP group later, the configuration takes effect.
virtual-address: Virtual IPv6 address. link-local: Indicates that the virtual IPv6 address of the VRRP group is a link local address. Usage guidelines The first virtual IPv6 address assigned to a VRRP group must be a link local address and only one such address is allowed in a VRRP group. After you remove all virtual IPv6 addresses, the VRRP group is automatically removed. The first address assigned to the group must be removed the last.
Usage guidelines The command is effective only when VRRP operates in load balancing mode. Before executing the command, create a VRRP group on an interface and configure the virtual IPv6 address of the VRRP group. When the status of the monitored track entry turns from negative to positive or invalid, the corresponding VFs automatically restore their weights. The track entry specified in this command can be nonexistent.

BFD configuration commands bfd detect-multiplier Use bfd detect-multiplier to configure the detection time multiplier. Use undo bfd detect-multiplier to restore the default. Syntax bfd detect-multiplier value undo bfd detect-multiplier Default The detection time multiplier is 5. Views Interface view Default command level 2: System level Parameters value: Detection time multiplier in the range of 3 to 50. Examples # Configure the detection time multiplier as 6 on GigabitEthernet 1/0/1.
Usage guidelines Do not configure the source IP address of the BFD echo packets to belong to the same network segment as any interface address of the device. Otherwise a large amount of ICMP redirect packets might be sent by the remote device, causing network congestion. Examples # Configure the source IP address of echo packets as 10.1.1.1. system-view [Sysname] bfd echo-source-ip 10.1.1.
Default command level 2: System level Parameters value: Minimum interval for receiving BFD control packets, in the range of 10 to 1000 milliseconds. The default is 400 milliseconds. Usage guidelines If the remote device sends BFD control packets at an interval shorter than the minimum receiving interval of the local device, the remote device changes its sending interval to the minimum receiving interval of the local device.
bfd multi-hop destination-port Use bfd multi-hop destination-port to configure the destination port number for multi-hop BFD control packets as 3784 or 4784. Use undo bfd multi-hop destination-port to restore the default. Syntax bfd multi-hop destination-port port-number undo bfd multi-hop destination-port Default The destination port number for multi-hop BFD control packets is 4784.
passive: Uses the passive mode. In the passive mode, BFD does not actively transmit a BFD control packet to the remote end; it transmits a BFD control packet only after receiving a BFD control packet from the remote end. Examples # Configure the session establishment mode as passive. system-view [Sysname] bfd session init-mode passive display bfd debugging-switches Use display bfd debugging-switches to display enabled BFD debugging switches.
