Using Layer 3 Routing
VLANs can significantly enhance network performance and security.
However, if you use conventional routers to interconnect VLANs, you can
lose most of your performance advantage. The TigerSwitch 10/100
provides wire-speed routing, which allows you to eliminate your
conventional IP routers, except for a router to handle non-IP protocols
and a gateway router linked to the WAN. Just assign an IP address to any
VLANs that need to communicate. The switch will continue to segregate
Layer 2 traffic based on VLANs, but will now provide inter-VLAN
connections for IP applications. This switch will perform IP routing for
specified VLAN groups, a directly connected subnetwork, a remote IP
subnetwork or host address, a subnetwork broadcast address, a switch IP
address on a specific IP subnetwork, or an IP multicast address.
