Detailed Description

NextHop is the generic class for holding information about routing next hops. NextHops can be of many types, including immediate neighbors, remote routers (with IBGP), discard interfaces, encapsulation endpoints, etc. NextHop itself doesn't really do anything useful, except to provide a generic handle for the specialized subclasses.
