I forgot to mention; this puts machine in a weird state. It can be connected to, via 10.0.15.128, but it can't initiate connections to outside. By removing routes:
# ip r d default via 10.0.15.253 dev br0 proto dhcp src 10.0.15.109 metric 100
# ip r d 10.0.15.253 dev br0 proto dhcp scope link src 10.0.15.109 metric 100

machine is usable again.
