Bridging Status Setup 
The bridging status in this field control entire system’s bridging behaviors. There are three modes of 
bridging: residentialrestricted, and unrestricted.

The residential bridging will direct packets coming from CPE side to be forwarded to the network 
side port without a lookup. This is the most commonly used mode. 
  
The restricted bridging will direct the packets undergo a MAC address lookup and if the destination is 
another CPE port, the packets would be dropped. Thus, CPE to CPE traffics are not allowed.   
 
The unrestricted bridging will force packets to be forwarded based MAC address lookup under all 
cases.
