Abstract:
1. A method of address assignment for a network element being operable in a multi-level network, comprising: retrieving a network prefix of said multi-level network and network prefix information including at least one of a top-level indication, a suffix length parameter and a maximum prefix length parameter, generating a first address in accordance with a topology of said multi-level network on a basis of said retrieved network prefix and network prefix information, assigning said generated first address to an egress interface of said network element, wherein, if said network element is not dedicated as a top-level network element of said multi-level network, said first address generating further comprises building an interface identifier of said egress interface, and concatenating said built egress interface identifier and said retrieved network prefix, and determining, on a basis of a length of said retrieved network prefix and said retrieved maximum prefix length parameter, whether or not said network element is dedicated as a bottom-level network element of said multi-level network.
