Issue Description
VRRP backup group runs abnormally, the service always intermits.
Alarm Information
In logs, the following information is always printed
System detected a vrrp config error of VIRTUAL IP ADDRESS ERROR
Handling Process
The problem is solved after modifying the group number of one virtual backup group, the configuration is
interface Ethernet3/0/0
ip address x.x.x.131 255.255.255.240
vrrp vrid 1 virtual-ip x.x.x.129
#
interface Ethernet3/0/2
ip address x.x.x.124 255.255.255.128
vrrp vrid 2 virtual-ip x.x.x.126
VRRP runs normally after modifying the configuration.
Root Cause
The configuration is：
interface Ethernet3/0/0
ip address x.x.x.131 255.255.255.240
vrrp vrid 1 virtual-ip x.x.x.129
#
interface Ethernet3/0/2
ip address x.x.x.124 255.255.255.128
vrrp vrid 1 virtual-ip x.x.x.126
check the logs：the following information appears frequently
%Aug 5 02:19:28 2004 NE40-UP VRRP/5/ConfigError:
System detected a vrrp config error of VIRTUAL IP ADDRESS ERROR
the system prompts to detect the virtual ip configuration error
because the two interfaces enable the virtual backup group 1，the configuration results in the backup group conflict, while the VRRP virtual backup group of NE40/80 is valid, so we cannot use the same virtual backup group number at the various interfaces.
