Greetings.
I have two VRRP equipment S6, regarding VRRP configuration is as follows:

- Router 1:

set gvrp disable
set spantree stpmode none

interface vlan 1
vrrp create 1 v2-IPv4
vrrp address 1 10.18.4.250
vrrp priority 1 200
vrrp enable 1

interface vlan 2
vrrp create 1 v2-IPv4
vrrp address 1 10.18.5.254
vrrp priority 1 200
vrrp enable 1

interface vlan 10
vrrp create 1 v2-IPv4
vrrp address 1 10.18.10.254
vrrp priority 1 200
vrrp enable 1

.
.
.

interface vlan 31
vrrp create 1 v2-IPv4
vrrp address 1 10.18.31.254
vrrp priority 1 200
vrrp enable 1


- Router 2:

set gvrp disable
set spantree stpmode none

interface vlan 1
vrrp create 1 v2-IPv4
vrrp address 1 10.18.4.249
vrrp priority 1 50
vrrp enable 1

interface vlan 2
vrrp create 1 v2-IPv4
vrrp address 1 10.18.5.253
vrrp priority 1 50
vrrp enable 1

interface vlan 10
vrrp create 1 v2-IPv4
vrrp address 1 10.18.10.253
vrrp priority 1 50
vrrp enable 1

.
.
.

interface vlan 31
vrrp create 1 v2-IPv4
vrrp address 1 10.18.31.253
vrrp priority 1 50
vrrp enable 1

By doing tests on the operation of VRRP do the following:

Connect the links to the "switch A" and works well on VVRP. The problem is when I connect to a second switch "switch B and switch C" where the connection on my device VLAN 2 fails.

What I can do that would generate this problem ?.

Thank you very much!.

Could you change yo normal triangular topology with two core switches running vrrp
And one edge switch . Stp used for l2 loop prevention
What is the model number of core switches .
There are many solutions available
Ex mlag , EAPS

Good day.

There are two S6 chassis firmware 07.22.02.001, currently the core B is not connected to Internet (10.18.4.254) and have that problem.

The switches A, B and C are swicthes stack C5 series.

Thanks.

You turned off STP on both routers. Regrading your picture you build a loop when adding a second or a third switch.

Kind regards

Like PARTHIBAN CHINNAYA said, you should think about re-designing you topology.E.g. put an additional direct connection between both routers and turn on stp. Or use VSB between the S-Series.
