Hi, I'm running the latest FreeBSD 6.1-RELEASE-p3 on the following piece of hardware:- IBM xSeries 336 - 1 add-on PCI dual-port NIC (IBM Netxtreme Dualpt Ethernet adapter) matching the Broadcom BCM5704C Dual Gigabit Ethernet chipset (detected as bge0 and bge1) - 2 internal built-in NICs matching the Broadcom BCM5721 Gigabit Ethernet chipset. (detected as bge2 and bge3) I run bridging on bge2 and bge3 as follows:- ROUTER o--o C650x o----- bge2 + bge3 -----o C3750G (SERVERS) *C650x = Cisco Catalyst C650x core switch *C3750G = Cisco Catalyst C3750G distribution switch In /etc/rc.conf:- ifconfig_bge2="up" ifconfig_bge3="up" cloned_interfaces="bridge0" ifconfig_bridge0="addm bge2 addm bge3 up" The bridge works OK:- bridge0: flags=8043<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 ether ac:de:48:b0:96:99 priority 32768 hellotime 2 fwddelay 15 maxage 20 member: bge3 flags=3<LEARNING,DISCOVER> member: bge2 flags=3<LEARNING,DISCOVER> My servers can reach the router via the server, and tcpdump on bridge0 confirms traffic being passed through OK. I had earlier planned to assign IP address to either bge0 or bge1 for SSH remote access and running other services, but due to another problem (on a separate thread) I am left with bge2 and bge3 as the only usable interfaces. So I tried to assign IP on the bridge interface as follows:- $ ifconfig bridge0 inet 192.168.1.18 netmask 255.255.255.0 broadcast 192.168.1.255 (192.168.1.0/24 is the subnet active on the particular VLAN I'm on in the Cisco switchports). The IP got assigned OK in bridge0, I can ping to it from inside the box. However when I tried to ping my other servers on bge3 side as well as the router on bge2 side, I get request timed out, i.e. the IP address is not reachable. Would appreciate any assistance.. thanks. :) --mendonan "Yang mimpikan secangkir kopi panas dengan selimut.." (Dreaming of a cup of hot coffee, and a blanket..")
