A method for supporting different types of networks or multiple logical networks within the same network. Every router in the network is capable of supporting several protocol stacks or several routing tables rather than requiring a router for each one. It enables virtual subnets within the network, each independent of the other. Virtual subnets combine the logical subdivision provided by layer 2 virtual LANs (VLANs) with the filtering and firewall benefits of layer 3 routing. In addition, virtual routing often allows the entire network to be viewed from a single management console.

- Brother MFC-5890CN
- From start to finish, the Brother MFC-5890CN leaves many unanswered questions in its wake: Who designed this eyesore? Why is it so expensive? Did they forget to test out the features before production? Whatever the answer, one thing is certain: we're unapologetically dissatisfied with this all-in-one printer/scanner/fax/copier. Don't be fooled...
