You can also load the module with: kldload if_bridge this command gives the output: module if_bridge already exists.. ... failed to register... bla bla (I have device if_bridge in my kernel setting so that already exists) IIRC, your settings in rc.conf should be enough to configure the bridge, so if you choose to load dynamically while running, try a /etc/netstart to configure the bridge. If that doesn't work, a reboot should. If you can't get it to work, supply the same output I asked for above, THE out put is the same for the above said commands and then I'll set up a quick lab here to test it.

RE: ping stucks/hangs on PCI 3com NIC sk0 interface but works on builtin NIC
Thanks dude, it helped me. if i configure the NICs with IPs belonging to different subnets, I get ping working locally. I can see multiple routes for different subnets in NETSTAT too. Now i assume that in order to configure the NICs with the same NETWORK and make them working i need to configure the System as router. Anyways, for now Thanks for your help ..

You are right, but it does not reply to ping even if i plug this to an external system with crossover cable and ping from that PC. Still not surprising. See below. that is the difference in behaviour of both NICs Note: bge0 is builtin NIC sk0 is 3com PCI NIC now after configuration of IPV4 Addresses, when i verify the configuration with ping if i ping bge0(ping 192.168.0.1) i get the response of success but when i ping sk0 (ping 192.168.0.2) Ping gets stuck and gives no response, neither it gives success or host unreachable or denied kinda errors.. Why do you want both interfaces to be configured on the same subnet? that is not required as such, I am just preparing the setup to use this machine a bridge and configure dummynet on this machine. You might try a different configuration for your testing. I suspect if you changed the IP address of sk0 to 192.168.1.2 or similar it would behave as you are expecting. it just hangs over there.. and i can juz see one line of ping not proceeding anyway. and if I terminate it via CTRL C then i get statistics sumthing like 3 packets sent, 0 received and 100% loss... This is probably expected behavior. What does netstat -rn show? My guess is that the route for 192.168.0.0/24 is link#1 aka bge0 and since it's not plugged in to anything that's as far as it gets. btu it does not show any other interface in netstat printout with this -rn switch and can you explain, how this is the expected behavior then..? There can only be one route at any time for any given network. When you bring up bge0 with 192.168.0.1 a route is automatically created for 192.168.0.0 pointing to that interface. When you then bring up sk0 with 192.168.0.2 no additional route can be added for 192.168.0.0 since there is already one present. Therefore ALL traffic destined for the 192.168.0.0 network will go out via bge0. In order to be able to ping 192.168.0.2 _locally_ you'd either need to connect the interfaces with a crossover cable (well, crossover isn't strictly necessary since gigabit ethernet adapters can figure it out on their own..) OR plug both interfaces into a switch/hub. Ping packet goes out bge0 (according to the route), across the wire and comes in on sk0 (destination address). The response would be delivered directly to bge0 (without going over the wire). Similarly, in order to be able to ping 192.168.0.2 from a second machine all _three_ interfaces would need to be connected to the same network segment (via a switch/hub, etc). Ping packet goes out from peer, across the wire and in on sk0 (destination address). Response goes out bge0 (according to route), across the other wire and back to the peer. I hope this helps you make sense of things.

No. A router's responsibility is to route packets between DISSIMILAR network prefixes. In essence, trying to do what you want is similar to this: - you live at 100 John St - you need to go to 50 John St - the street is addressed in a way that a 50 John street is to your left AND to the right Which way do you go?
