Abstract
In one embodiment, a method comprises: creating, by a root network device in a wireless data network, a perimeter topology comprising a first distance vector-protocol path of a first group of perimeter devices and a second distance vector-protocol path of a second group of the perimeter devices, the creating comprising outputting first and second advertisement messages causing the perimeter devices to attach to only one parent of only one of the first or second distance vector-protocol paths and a junction device to attach at respective ends of the first and second distance vector-protocol paths; and causing the junction device to forward, from the first distance vector-protocol path, a data packet toward the root network device via the second distance vector-protocol path.
