Bridge not working

view story

http://unix.stackexchange.com – We want to create bridge (mybridge) on our board over eth0 and eth1 interface. The board runs Linux Following are the commands: brctl addbr mybridge ifconfig eth1 ifconfig eth0 brctl addif mybridge eth1 brctl addif mybridge eth0 ifconfig mybridge up PC-----ETH1-----mybridge-------ETH0 When we ping the board from a PC, we are able to receive packet on eth1 (eth1 rx counter increasing), but they are not getting transferred to mybridge, since the rx counter on mybridge is not increasing. After little search on net we found that mybridge is up but not going to RUNN (HowTos)
