A cascaded stack of routing units each of which routes packets that it receives at its external ports and which conduct an election for a lead router that lends network and media access control addresses to the router interfaces of the other units in the stack. These other subordinate units have selected ancillary functions suppressed but otherwise have full routing capability. A packet entering the stack and requiring routing is routed by the unit that receives it and is thereafter bridged to its egress port. |
