Tagged VLAN interface does not allow routing without IP configuration on it
 
Dear all

I have a Linux Centos EL5 2.6.18-162 kernel.

I have bridge interface and tagged VLAN on it to see some traffic.

I want to enter a routing to define which network is on that VLAN. I could not give IP address from that VLAN, because, VLANs are divided into 4 IP subnets and most of them have no free IP.

bridge-utils-1.1-2
iproute-2.6.18-7.el5
iputils-20020927-43.el5
vconfig-1.9-2.1


what is my problem, here?

I think you need to have the vlans on the ethernet interfaces and then bridge them together rather than trying to vlan a bridge interface.
