Assigning IP to a bridged interfaces

Question

Is there a way to assign an IP to bridged interfaces? For example, under normal circumstances:

ifconfig eth0 0.0.0.0
ifconfig eth1 0.0.0.0
brctl addbr mybridge
brctl addif mybridge eth0
brctl addif mybridge eth1

So is there a way to either:

• (a) assign IPs to eth0/eth1?
• (b) if not, then is there any other way around this problem?

I want to some how bridge interfaces having IPs.

Solution 1

You can directly assign a new IP address to your bridge:

ip addr add 192.168.0.2/24 brd + dev br0

You also may need to configure a route for the internet connection:

route add default gw 192.168.0.1 dev br0

Note: replace the provided IP address in the above examples by the proper one for your subnet.

Solution 2

An interface that is a member of a bridge cannot have IPs assigned to it directly. You assign an address to the bridge interface instead, e.g.

ifconfig br0 0.0.0.0
