Hi@akhtar,

As the above error message says, you should specify the bridge_interface for creating a network. So the command goes as below. Lookout for ‘–bridge_interface=br100‘

[root@gcontroller]#nova-manage network create tg-network --multi_host=T --fixed_range_v4=10.180.14.160/27 --bridge_interface=br100 --num_networks=1 --network_size=256

[root@gcontroller]# nova net-list

Hope this will work.

Thank You
