I don't understand ?

Each vm (tapXXX.. interface, maybe my schema was not clear) see traffic on his bridge, but no other bridge.

eth0.2 ---- vmbr0v2 --- tap1i0
                    --- tap2i0
eth0.3 ---- vmbr0v3 --- tap3i0
                    --- tap4i0
eth0.3 ---- vmbr1v3 --- tap5i0



so

tap1i0 can ping tap2i0
tap3i0 can ping tap4i0
tap3i0 can't ping tap5i0  (same vlan but different bridge)


bridges doesn't pass traffic across them because of

net.bridge.bridge-nf-call-ip6tables = 0
net.bridge.bridge-nf-call-iptables = 0
net.bridge.bridge-nf-call-arptables = 0
net.bridge.bridge-nf-filter-vlan-tagged = 0

so we have isolation inside bridge
