Problem VRRP with VLAN.

[Luis_Bernal]

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
