Chapter 10 Interface
If computer B responds to computer A, bridge X records the source address
0B:0B:0B:0B:0B:0B and port 4 in the table. It also looks up 0A:0A:0A:0A:0A:0A in the table
and sends the packet to port 2 accordingly.

Bridge Interface Overview
A bridge interface creates a software bridge between the members of the bridge interface. It
also becomes the ZyWALL's interface for the resulting network.
A bridge interface may consist of the following members:
• Zero or one WLAN interfaces
• Zero or one VLAN interfaces (and any associated virtual VLAN interfaces)
• Any number of Ethernet interfaces (and any associated virtual Ethernet interfaces)
When you create a bridge interface, the ZyWALL removes the members' entries from the
routing table and adds the bridge interface's entries to the routing table. For example, this table
shows the routing table before and after you create bridge interface br0 (250.250.250.0/23)
between lan1 and vlan1.

Table 78 Example: Routing Table Before and After Bridge Interface br0 Is Created

IP ADDRESS(ES)
210.210.210.0/24
210.211.1.0/24
221.221.221.0/24
222.222.222.0/24
230.230.230.192/26
241.241.241.241/32
242.242.242.242/32
In this example, virtual Ethernet interface lan1:1 is also removed from the routing table when
lan1 is added to br0. Virtual interfaces are automatically added to or remove from a bridge
interface when the underlying interface is added or removed.
