Bridge Summary - ZyXEL Communications ISG50-ISDN User Manual

• 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 ISG50 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 76 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.
