Abstract
Some embodiments provide a method for determining a router identifier for a centralized routing component of a logical router. The method determines that a dynamic routing protocol is enabled for the centralized routing component. When a router identifier was previously stored for the centralized routing component, the method assigns the stored router identifier as the router identifier for the centralized routing component only when the stored router identifier matches one of a set of valid addresses for the centralized routing component. When the centralized routing component does not have a previously stored router identifier that matches one of the set of valid addresses, the method assigns one of the set of valid addresses as the router identifier for the centralized routing component according to a hierarchy among the set of valid addresses.
