I have read several articles for setting up a network bridge. My configuration is: WorkStation --> Switch0:VLAN1 --> Switch1:VLAN1 --> bridge --> Switch1:VLAN45 --> Laptop I am running CentOS 4.3 on the bridge #> brctl show bridge name bridge id STP enabled interfaces br0 8000.0030843e5aa2 no eth1 eth2 I followed the instructions at : http://www.linuxjournal.com/article/8172 I can't ping the laptop nor can the laptop ping my workstation. I put an IP on br0 and tried to ping out and got nothing. tcpdump shows no traffic except for an arp request from the laptop. Was I supposed to recompile my kernel? I saw at least one article that recommended recompilig the kernel with a couple of config changes. I have the latest stock 2.6 kernel RPM installed. Do I need to do any special configuration on the switches like setting the port to do port monitoring or anything like that? Its a Cisco 2900 switch. Any help would be appreciated.
