Cluster VRRP

I have a question clustered together with VRRP . 2 concentrators have PPPoE running OSPF is only 80 % (1.700 pppe clients) and the other with 8 % (30 PPPoE clients) . Came the idea of the cluster with VRRP to beyond backup , have the balance of services.

Today my concetratores have these lower line IPs that are the gateways of PPPoE clients :
R1 Wan: Ether1 189.200.x.1 / 28
R2 Wan: Ether1 189.200.x.2 / 28

Now follows the setting made :

R1 configuration:
/ip address add address=172.16.68.1/24 interface=ether1

/interface vrrp add interface=ether1 vrid=49 priority=254

/interface vrrp add interface=ether1 vrid=77

/ip address add address=189.204.68.1/28 interface=vrrp1

/ip address add address=189.16.204.68.2/28 interface=vrrp2

R2 configuration:

/ip address add address=172.16.68.2/24 interface=ether1

/interface vrrp add interface=ether1 vrid=49 priority=254

/interface vrrp add interface=ether1 vrid=77

/ip address add address=189.204.68.1/28 interface=vrrp1
/ip address add address=189.16.204.68.2/28 interface=vrrp2

I even seem to get up when I turn off one another takes but the balancing and the cluster itself is not working. From what I understand, it was to CCR1038 with high processing divide customers to balance the load . Another important point is that when I include some information , I was sure it was also included in other ccr1036 .

I HA running on linux and just need to move server in a system to synchronize to the other. I thought the router OS would be so . If anyone can help me I will be very grateful!
