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 ES3628EA 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.
