Hi,

According to the first error message, the subnet you try to unbind is used
in router routes, you can see current router routes using:

   *neutron router-update **2f16d846-b6aa-43a3-adbe-**7f91a1389b7f*

you need to update them before unbind:

*   neutron router-update **2f16d846-b6aa-43a3-adbe-*
*7f91a1389b7f --routes type=dict list=true destination=...,nexthop=...
[destination=...,nexthop=...[...]]*
or clear router routes:



*   neutron router-update 2f16d846-b6aa-43a3-adbe-7f91a1389b7f --routes
action=clear*
And finally retry to unbind the subnet.
