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 failed that I ping pc1 from pc0. I input brctl command , and get these infomations: **************************************************************************************** # ./brctl show bridge name bridge id STP enabled interfaces vb 8000.0050c20c3000 no eth0 eth1 # ./brctl showmacs vb port no mac addr is local? ageing timer 1 00:16:17:4c:7b:4e no 65.66 1 00:16:17:91:6f:0b no 36.87 1 00:16:17:91:6f:0c no 292.78 1 00:17:31:49:2c:7a no 223.91 1 00:17:31:4a:4d:bd no 14.28 1 00:30:4f:26:8c:bb no 165.50 1 00:40:71:00:43:2a no 4.84 1 00:40:71:00:43:8e no 3.70 1 00:50:c2:0c:30:00 yes 0.00 /* eth0 */ 2 00:50:c2:0c:30:01 yes 0.00 /* eth1 */ # ./brctl showstp vb vb bridge id 8000.0050c20c3000 designated root 8000.0050c20c3000 root port 0 path cost 0 max age 20.00 bridge max age 200.00 hello time 2.00 bridge hello time 20.00 forward delay 150.00 bridge forward delay 15.00 ageing time 300.00 hello timer 0.29 tcn timer 0.00 topology change timer 0.00 gc timer 0.09 flags eth0 (1) port id 8001 state forwarding designated root 8000.0050c20c3000 path cost 19 designated bridge 8000.0050c20c3000 message age timer 0.00 designated port 8001 forward delay timer 0.00 designated cost 0 hold timer 0.00 flags eth1 (2) port id 8002 state forwarding designated root 8000.0050c20c3000 path cost 100 designated bridge 8000.0050c20c3000 message age timer 0.00 designated port 8002 forward delay timer 0.00 designated cost 0 hold timer 0.00 flags ****************************************************************************************** Does anyone tell me how to set it ?
