1. A method comprising: facilitating, by at least a subset of a plurality of nodes, communication of a mobile ad hoc network (MANET), the nodes configured as a virtual Internet Protocol (IP) network, the virtual IP network comprising a plurality of physical paths of the MANET, each physical path coupling an IP network to an IP node, each physical path traversing a distinct set of nodes of the MANET; and representing, to the IP network, the physical paths of the virtual IP network as a logical path comprising one or more virtual IP nodes, adding a physical path to the physical paths of the virtual IP network; determining with a node of the distinct set of nodes of the MANET whether responsive to the addition of the physical path, a previously unreachable IP node has become reachable, and sending a notification from the node of the distinct set of nodes of the MANET to at least one IP node that indicates that the previously unreachable IP node has become reachable.
