10.5.2 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 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 ge1 and vlan1.

Table 56 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 ge1:1 is also removed from the routing table when
ge1 is added to br0. Virtual interfaces are automatically added to or remove from a bridge
interface when the underlying interface is added or removed.
