According to one embodiment, a routing tree may be determined by facilitating communication of a first network and a second network. The first network comprises first switches and uses a first routing protocol, and the second network comprises second switches and uses a second routing protocol. The intersection of the first and second switches comprises gateway switches. A gateway switch enables creation of a second routing tree of the second routing protocol. The second routing tree has virtual links and a virtual root switch representing a first root switch of the first network. The second switches generate minimum link cost tunnels using information from the second routing protocol. A first routing tree of the first routing protocol is extended with the tunnels to merge the first routing tree and the second routing tree. |
