Hi, would this not be covered fairly well by a combination of Link
Aggregation (802.ad) Spanning Tree along with carp. That way you have
your 4 gige ports in a aggregate group with a second redundant aggregate
group for failover. Then having another layer of failover with carp, or
something along those lines. It would need some modifications to the
code but i think less than the schema you envisage.
