In the left portion of this figure, a conventional router is used to enable inter-VIAN communien- tions. Because one port is required per VLAN, this configuration can be costly as well as detrimental to router performance. In contrast, a router with a global port, illustrated in the right portion of the figure, can support multiple IP subnets on a single port.
