Abstract
A first switch in a network is provided. During operation, the first switch can receive traffic associated with a virtual network address allocated to the first switch and a second switch. The first and second switches can provide high availability to each other. If a layer-3 static multicast route is received at the first switch for a multicast group, the first switch can configure the static multicast route in the control plane. The first switch can determine that a set of conversion conditions are satisfied for the static multicast route. The set of conversion conditions can be applicable to a respective switch associated with the virtual network address. If the set of conversion conditions is satisfied, the first switch can generate a set of layer-2 entries for the multicast group from the static multicast route and program the forwarding hardware to include the set of layer-2 entries.
