Retrieved from "https://wiki.openstack.org/w/index.php?title=Neutron/FWaaS/API&oldid=24623" By default, all security groups contain a series of basic (sanity) and AttributeInfo wraps an API resource's attribute dict and provides methods for filling defaults, validating, converting, etc. Extension generates and returns a response with a list of networks as well as a nested list of subnet information in each network. Tag service plugin allows users to set tags on their resources. These networks connect as IPv6 routers and forwarding IPv6 traffic for other instances.
