To go right out and say it...you really shouldn't be running dante and AVB on the same network. That said, i have, on my bench, gotten dante and cobranet (AVB's grampa) to coexist happily on the same network, but would never deploy a configuration like that in the wild though.
I worked on a very large converged AVB and Dante network (1k+ channels) that was successful using Extreme Networks enterprise-grade switches. There was even some Cobranet for the paging system but I recall we kept it on its own switch. It was not for the feint of heart or probably everyday users - it required a strong integration team and extensive manufacturer support both from Biamp and Extreme, but it worked in the end.
