ABSTRACT:
The invention relates to a routing apparatus for routing data packets in a network comprising a sub-network, in particular a broadcast sub-network. The routing apparatus is included in a first network element of the sub-network, the first network element being arranged to support first and second protocol sets, for example OSI protocols and IP protocols. Upon designation of the first network element to represent the other network elements in the sub-network in respect of the first and second protocol sets, the routing apparatus is arranged to create a respective routing data packet for each protocol set and to cause the routing data packets to be propagated through the network. Upon resignation of the first network element as representative in respect of one of the protocol sets, the routing apparatus is arranged to cause the respective routing data packet for that protocol set only to be purged from the network.
