Good morning I started with OpenSack implementation Ubuntu 14lts icehouse, of course, I m new in all this I followed the guide icehouse and in the chapter of virtual nets with neutron in a controller node I can create the virtual nets with users "admin" and "demo" "neutron subnet-create ext-net --name ext-subnet \ --allocation-pool start=203.0.113.101,end=203.0.113.200 \ --disable-dhcp --gateway 203.0.113.1 203.0.113.0/24" "neutron subnet-create ext-net --name ext-subnet \ --allocation-pool start=203.0.113.101,end=203.0.113.200 \ --disable-dhcp --gateway 203.0.113.1 203.0.113.0/24" The problem is I want delete all configuration and again start and use others ip range. With this commands I delete all neutron router-delete "router name" neutron subnet-delete "subnet name" neutron net-delete "net name" but does not work, the virtual router and your ip 192.168.1.1 continues to receive response even restarted the neutron service but not updated the configuration Do not know, can you help me and telling me that other configuration is necesary for clear all and back to start? Thanks you and regards
