NETWORK PLANNING

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 TigerStack 1000 switches are routing switches that provide 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. The switch will perform IP routing for specified VLAN groups, a directly connected subnetwork, a remote IP subnetwork or host address, or an IP multicast address.
