Hello,
I'm trying to get bridging to work between eth0 and usb0:
192.168.13.2 <---> br0:192.168.13.47 <---> 192.168.13.1
usb0 eth0
192.168.13.2:~ # ping 192.168.13.1
... 100 % packet loss
On 192.168.13.1 I do see the arp requests but no icmp packet :-/
Just like "No traffic gets trough (except ARP and STP)" in the
FAQ on http://www.linux-foundation.org/en/Net:Bridge
Except ...
I can ping 192.168.13.1 from the bridge (192.168.13.47)
Trying to ping 192.168.13.2 from the bridge does not work
I do see the arp requests for 192.168.13.2 on 192.168.13.1 (!)
I get the same result if if enable STP on the bridge.
What is going wrong here? :-/
Any hint appreciated!
Regards,
andreas
PS: The bridge system is a SUSE 10.2 with kernel 2.6.18.8-0.7-default
(incl.
suse patches) usb0 is a MosChip usb nic using the mcs7830 driver and eth0
is
an on board intel nic. both work fine in non bridging mode.
my routing table (just ignore the vmnet stuff):
bibo:/proc/sys/net/ipv4 # route -n

How I set up the bridge:
# ifconfig usb0 0.0.0.0 down
# ifconfig eth0 0.0.0.0 down
# brctl addbr br0
# brctl addif br0 eth0
# brctl addif br0 usb0
# ifconfig br0 192.168.13.47 up
# brctl show br0
bridge name bridge id STP enabled interfaces
br0 8000.000d6080dcd6 no eth0
usb0
