Through the static IP routing feature, you can configure the Campus-REX as
an IP router with statically programmed route entries. You can enable this
function as a security feature to prevent eavesdropping and to provide
broadcast filtering, as well as to specify multiple destination gateways. When
static IP routing is enabled, you can access only specific remote IP subnets or
hosts.
Since IP routers make forward or filter decisions based on the network-layer
IP address instead of the MAC hardware address, MAC-level broadcast
frames are prevented from reaching unwanted destinations in the network.
The following example shows a simple Internet Service Provider (ISP) site
that uses the static IP routing feature to filter MAC-level broadcast frames
sourced by ISP Subscriber A from reaching ISP Subscriber B. In this
example, all frames from Subscriber A and Subscriber B are directed to the
router at the Network Access Provider site. From there, frames from both
subscribers are forwarded directly to the Internet.
