Issue Description
Two USG5300 and two S9300 switch are in the square-shaped network. USG5300 to two S9300 two VRRP, the two S9300 to two USG5300 do VRRP.


Phenomenon:
VRRP port appeared in USG5300 the display hrp state found and S9300 connected peer down (screenshot in the attachment), VRRP not established. USG5300 appear the error information. System detected a vrrp config error of VIRTUAL IP ADDRESS ERROR, Virtual Router: 2
Alarm Information
NULL
Handling Process
It found that two S9300 switch's VRRP ID is 2, the VRRP ID used consisting of two USG5300.

Because the devices at both sides use the same network segment to negotiate VRRP, resulting in 2 groups VRRP negotiation confusion, it appeared the phenomenon of peer down.
Root Cause
According to the error message, you can determine the errors caused by VRRP 2 vrrp configuration. It may because that VRRP virtual address VRRP address, VRRPID or two identical devices does not match.
