    Just giving them the same priority does not give you active-active. When two VRRP routers have the same priority the one with the higher MAC wins. So only one of them will become master. You have to block the VRRP hellos via an ACL on the ISC link.

    VRRPActive.pol

    entry denyVrrpCtrl {

    if match all {

    destination-address 224.0.0.18/32;

    } then {

    deny; } }

    Fabric Routing is a simpler approach, imho. During the VRRP config, this is an option you can turn on.

    configure vrrp {vlan vlan_name vr vr_id | all} fabric-routing [on | off]

    Stephane is right. With the introduction of fabric routing we have an easier approach. The ACL was the way to do it before we had fabric routing. Anyway, both ways work.
