ADC Campus-REX2 RS Manuale Utente

To enable or disable Spanning Tree, see 

. The following elements are required for managing the 

Spanning Tree active topology:

assigning a priority to each bridge relative to all bridges within the 
bridged LAN

assigning a priority to each bridge port relative to all ports on a bridge

assigning a path cost to each port

The Campus-REX2 offers both dynamic and static routing.

Through the static IP routing feature, you can configure the Campus-REX2 
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.
