Inter vrrp-group routing

Hi All,

We are working on a migration project from Cisco to Juniper, under the Cisco devices, the HSRP groups were configured on a single interface and all could talk across to each other.  After porting the configuration to an MX device, the inter vrrp-group traffic is no longer working.  Inbound and outbound traffic from all groups is working as expected.

Juniper recommendation was to convert to trunk and units, however as this is a large architecture, modifying the downstream switches where these type of configs are in place is going to be tedious.

Anyone have any ideas?

interfaces {
  ge-106/0/21 {
    delete: disable;
    apply-groups [ CUSTOMER-IXXXX CUSTOMER-VRRP-XX-PRIMARY CUSTOMER-VRRP-XX-PRIMARY ];
    mtu 9000;
    description "xxxxx--";
    unit 0 {
      vlan-id 4094;
      family inet {
        policer {
          input LIMIT-200MEG;
          output LIMIT-200MEG;
        }	  
        address XXX.XXX.XXX.18/28 primary {
          vrrp-group 204 {
            virtual-address XXX.XXX.XXX.17;
	    authentication-key xxxxxx;
          }
        }
        address XXX.XXX.XXX.114/28 {
          vrrp-group 214 {
            virtual-address XXX.XXX.XXX.113;
	    authentication-key xxxxxx;
          }
        }
		address XXX.XXX.XXX.130/27 {
          vrrp-group 224 {
            virtual-address XXX.XXX.XXX.129;
	    authentication-key xxxxxx;
          }
        }
      }
      family inet6 {
        policer {
          input LIMIT-200MEG;
          output LIMIT-200MEG;
        }	  
      }
    }
  }
}
