Abstract
For a network including multiple host machines that each execute a number of network functions some embodiments provide a method for the network functions to advertise the availability of the network function and network addresses (e.g., internet protocol (IP) addresses) associated with the network functions to the other network functions using application programming interfaces (APIs). In some embodiments, non-routing network functions advertise their availability and/or network addresses associated with the network function to a routing network function (e.g., a routing network function that is part of a service router) for the routing network function to advertise to other network elements (e.g. other routing elements or other network functions that need to reach the advertising network function). These advertisements, in some embodiments, are part of participation in a dynamic routing protocol.
