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.

Table 5 Backup state of the active interface State Description MUP The active interface is working correctly for data transmission. MUPDELAY The active interface is experiencing a delay before it transits from the non-working state to the working state to take over. At this time, the standby interface is still active.

Track ID: 3 Status: Negative Duration: 0 days 0 hours 0 minutes 32 seconds Notification delay: Positive 20, Negative 30 (in seconds) Reference object: Track interface : Interface status : Inserted Interface : Ethernet1/2 Protocol : IPv4 Table 9 Command output Field Description Track ID ID of a track entry.

Field Description Physical status or Layer 3 protocol status of the monitored interface: Protocol • None—Physical status of the monitored interface. • IPv4—IPv4 protocol status of the monitored Layer 3 interface. • IPv6—IPv6 protocol status of the monitored Layer 3 interface.
When you configure collaboration between Track and BFD, do not configure the virtual IP address of a VRRP group as the local or remote address of a BFD session. Associating a track entry with the echo-mode BFD session detects a directly connected link. Before that, you must configure the source IP address of BFD echo packets. Examples # Create track entry 1, which uses BFD to monitor the link between local IP address 192.168.40.2 and remote IP address 192.168.40.1 by sending BFD echo packets.

The negative-time argument represents the delay time, in the range of 1 to 300 seconds. positive positive-time: Specifies the delay time for the Track module to notify the application modules that the status of the track entry changes to Positive. The positive-time argument represents the delay time, in the range of 1 to 300 seconds.
negative negative-time: Specifies the delay time for the Track module to notify the application modules that the status of the track entry changes to Negative. The negative-time argument represents the delay time, in the range of 1 to 300 seconds. positive positive-time: Specifies the delay time for the Track module to notify the application modules that the status of the track entry changes to Positive. The positive-time argument represents the delay time, in the range of 1 to 300 seconds.
ipv4: Monitors the IPv4 protocol status. When the IPv4 protocol status of an interface is up, the status of the track object is Positive. When the IPv4 protocol status of an interface is down, the status of the track object is Negative. To display the IPv4 protocol status of an interface, use the display ip interface brief command. ipv6: Monitors the IPv6 protocol status. When the IPv6 protocol status of an interface is up, the status of the track object is Positive.

Views Interface view Default command level 2: System level Parameters virtual-router-id: Specifies a VRRP group by its number in the range of 1 to 255.
Default A VRRP group is not associated with any track entry. Views Interface view Default command level 2: System level Parameters virtual-router-id: Specifies a VRRP group number in the range of 1 to 255. track track-entry-number: Specifies a track entry by its number in the range of 1 to 1024. forwarder-switchover member-ip ip-address: Enables the LVF on the router to take over the role of the AVF at the specified IP address immediately after the specified track entry changes to the negative state.
# Associate VRRP group 1 on Ethernet 1/1 with track entry 2 and enable the LVF to take over the role of the AVF at the IP address of 10.1.1.3 immediately after the specified track entry changes to the negative state. [Sysname-Ethernet1/1] vrrp vrid 1 track 2 forwarder-switchover member-ip 10.1.1.3 Related commands • display vrrp • vrrp vrid track interface vrrp vrid track interface Use vrrp vrid track interface to configure to track the specified interface.
When the status of the tracked interface turns from down or removed to up, the corresponding router automatically restores its priority. The interface specified in this command can be a Layer 3 Ethernet interface, a VLAN interface, a synchronous/asynchronous serial interface, a POS interface, an MP-group interface, a dialer interface, a BRI interface, or an HDLC link bundle interface.
A VRRP group operates correctly only when the configured virtual IP address and the interface IP address belong to the same segment and are legal host addresses. If they are not in the same network segment, 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 .
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.
Usage guidelines If you do not specify the verbose keyword, only the brief state information of VRRP groups is displayed. If you specify both an interface and a VRRP group, only the state information of the specified VRRP group on the interface is displayed. If you only specify an interface, the state information of all the VRRP groups on the interface is displayed. If you specify neither, the state information of all the VRRP groups on the router is displayed.
# When VRRP operates in standard mode, display detailed information about all VRRP groups on the router.
