In Massive Data Centers, BGP-SPF and similar routing protocols are used to build topology and reachability databases. These protocols need to discover IP Layer 3 attributes of links, such as logical link IP encapsulation abilities, IP neighbor address discovery, and link liveness. This Layer 3 Discovery and Liveness protocol collects these data, which may then be disseminated using BGP-SPF and similar protocols.
