Why does the ping to the virtual IP address of the VRRP group fail

1

Possible causes are as follows:
-VRIDs conflict.
-Pinging virtual IP addresses is disabled. Huawei firewalls enable you to ping virtual IP addresses by default. If ping virtual IP address is disabled, run the vrrp virtual-ip ping enable command.

Why cannot the virtual IP address of a VRRP group be pinged
Check whether the vrrp virtual-ip ping disable or undo vrrp virtual-ip ping enable command is configured on an S series switch. If so, run the vrrp virtual-ip ping enable command to allow the master device to respond to ping packets sent to the virtual IP address.

Whether S series switches support ping to the virtual IP address of the VRRP group
S series switches (S1700 excluded) allow user devices to ping a virtual IP address to serve the following purposes: - Monitors the operating status of the master in a VRRP group. Monitors communication between a user device and a network connected by a default gateway using the virtual IP address. Run the vrrp virtual-ip ping enable command to enable the ping to the virtual IP address.

Problem and solution when the firewall cannot ping the virtual IP address of the VRRP group
Possible causes are as follows: A VRID conflict occurs. The virtual IP address ping function is disabled. According to RFC3768, the ping command cannot be used to detect the virtual IP address connectivity. Huawei provides the virtual IP address ping function for the convenience of monitoring. This function is enabled by default. If it is disabled, you can run the vrrp virtual-ip ping enable command to enable it.

Configuring virtual IP addresses of VRRP groups on the USG6000

Number of virtual IP addresses of VRRP groups that can be configured on the USG6000
Example for configuring VRRP load balancing (configuring multiple virtual IP addresses) Requirements: USG_A serves as the Master of VRRP group 1 and the Backup of VRRP group 2. USG_B serves as the Master of VRRP group 2 and the Backup of VRRP group 1. On the internal network, HostA uses VRRP group 1 as the gateway, and HostC uses VRRP group 2 as the gateway. This helps implement load balancing and mutual backup. Configuration roadmap 1. Create two VRRP groups at GigabitEthernet 0/0/2 of USG_A. USG_A serves as the Master of VRRP group 1 and the Backup of VRRP group 2. 2. Create two VRRP groups at GigabitEthernet 0/0/2 of USG_B. USG_B serves as the Backup of VRRP group 1 and the Master of VRRP group 2. Operation steps 1. Configure VRRP. # Configure GigabitEthernet0/0/2 on USG_A, create VRRP group 1, and set the priority of USG_A in VRRP group 1 to 105 (as the Master). Create VRRP group 2 and set the priority of USG_A in VRRP group 2 to the default value 100 (as the Backup). system-view [USG_A] vrrp mode [USG_A] interface GigabitEthernet 0/0/2 [USG_A-GigabitEthernet0/0/2] ip address 10.1.1.1 24 [USG_A-GigabitEthernet0/0/2] vrrp vrid 1 virtual-ip 10.1.1.111 [USG_A-GigabitEthernet0/0/2] vrrp vrid 1 priority 105 [USG_A-GigabitEthernet0/0/2] vrrp vrid 2 virtual-ip 10.1.1.112 # Configure GigabitEthernet0/0/2 on USG_B, create VRRP group 1, and set the priority of USG_B in VRRP group 1 to the default value `100 (as the Backup).
