Hello, My experience suspects the use of dummy itself - I have seen strange things happening while using it for more than basic stuff. I would suggest running tcpdump on dummy0 and examine if ICMP replies (or neighbour information for that matter) are being sent. You could also try bridging with a real interface (perhaps try some veth combo).
If vmware-bridge creates a br-interface like brctl does, you could also try assigning your XX::1 ip to that interface.
