Abstract:
1. An article of manufacture including a non-transitory computer-readable medium having instructions stored thereon that, in response to execution by a computing device, cause the computing device to perform operations comprising: receiving a message indicating a connection of a host to a first flooding domain, the message including routing information for the host, wherein the routing information is encapsulated in a first Open Shortest Path First (OSPF) message type; wherein the message is formatted to prevent propagation of the routing information outside the first flooding domain or formatted to prevent propagation of the routing information outside a communication backbone coupling the first flooding domain and a second different flooding domain; translating the first OSPF message type into a second different OSPF message type according to whether an Internet Protocol (IP) address included in the routing information belongs to a particular subnet; and if the first OSPF message type is translated into the second different OSPF message type, then transferring the routing information encapsulated in the second OSPF message type over the second flooding domain or over the communication backbone.
