Event Details

An exciting new feature was just added to OpenStack Neutron in the Mitaka release; it's called address scopes. Address scopes build from the subnet pools feature added in Kilo. While subnet pools give us a mechanism for controlling the allocation of addresses to subnets, address scopes give Neutron a way to know where addresses are viable. They are also the thing within which addresses are not allowed to overlap. In this talk, we will give a quick review of subnet pools and then talk about how they support address scopes. Address scopes are key to overcoming the problem of "bring your own addressing" (BYOA) and are instrumental in determining where traffic should be blocked or where net address translation (NAT) should be applied (or not). This is especially important when designing your cloud for IPv6. Finally, we will briefly discuss the relationship between address scopes and two other exciting new features in Neutron: "BGP dynamic routing" and "routed networks."
