Chapter 9 Interfaces
ZyWALL ATP Series User’s Guide
271
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 Zyxel Device 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.
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.
9.8.1 Bridge Summary
This screen lists every bridge interface and virtual interface created on top of bridge interfaces. If you
enabled IPv6 in the Configuration > System > IPv6 screen, you can also configure bridge interfaces used
for your IPv6 network on this screen. To access this screen, click Configuration > Network > Interface >
Bridge.
