The interface has to go through the Spanning Tree Protocol (STP) initialization process to get into the forwarding state which takes a while (and it has to be marked up).

Well since bridging is at the link, not network layer you shouldn't do that. If it panic's send the console log (backtrace) and it will get fixed. > Can we give IP to dummy ethernet device? No, bridging is at layer 2 not layer 3.

How is this different from the existing dummy device which works fine in a bridge?
