dear all:
I try to configure a bridge in my embedded linux. I had fininshed
these operations below:
1) configure kernel, select the option "802.1d bridge"
2) compile bridge-utils
3) issue these commands:
ifconfig eth0 0.0.0.0
ifconfig eth1 0.0.0.0
brctl addbr vb
brctl addif vb eth0
brctl addif vb eth1
ifconfig vb 192.168.110.24 up
4) cd /proc/sys/net/bridge
for x in bridge-*; do echo 0 > $x; done
5) Then I connect PC0 to the eth0, and connect PC1 to eth1. The PC0
IP is 192.168.110.22, the PC1 IP is 192.168.110.60. It is successful ping
192.168.110.24(bridge) from PC0, It is failed ping 192.168.110.24 from PC1,
and failed ping PC1 from PC0.
I input brctl command , and get these infomations:

6) test bridge
It is successful ping 192.168.110.24(bridge) from PC0.
It is failed ping 192.168.110.24 from PC1.
It is failed ping PC1 from PC0.
