Hi all.
I have been digging through the mailing list archives and google for the past
couple of days looking for an answer, but have had little success.
here's my network setup.
i have a t-1, a cisco 2630 router, several hp4000M switches, and 2 VLAN
segments. i need to make 2 bridges on a i386 (750 athlon, RH72, 2.4.16, latest
from bridge.sf.net, 3c59x). yes, i know that there is the whole VLAN thing but
i am using TC so i need to break it up this way for various reasons (and my
problems are before i try to initiate TC). also, because i thought that it
might be the router, i tried it again between 2 of these switches and same
results (all traffic on the vlans is untagged)
anyway, here is a little pic (sorry if it looks distored) to help explain.
|---10.2/16--| eth0,eth1 |-----
---WAN-----ROUTER------| | bridge box | | hp4000M switch(vlans)
|---10.1/16--| eth2,eth3 |-----
i set up the bridges this way
brctl addbr br0
ifconfig eth0 0.0.0.0 up
ifconfig eth1 0.0.0.0 up
brctl addif br0 eth0
brctl addif br0 eth1
ifconfig br0 0.0.0.0 up
brctl addbr br1
ifconfig eth2 0.0.0.0 up
ifconfig eth3 0.0.0.0 up
brctl addif br1 eth2
brctl addif br1 eth3
ifconfig br1 0.0.0.0 up
i have also tried this without the 0.0.0.0 (just ifconfig eth/br up), and with
stp off. i have tried with addresses on the bridges and ethX.
the problem is that no matter how i shuffle it around, the bridge created on
10.2/16 only works if the bridge on 10.1/16 is down. it doesnt matter which i
make br0 or which i add first. if i bring up the bridge on 10.1, it just dont
work. tcpdump -i on 10.1 shows all the normal traffic. same thing on 10.2
shows only arp and netbios-datagrams.
this is really weird. i have replaced the nics thinking that one could be bad.
i have made sure that each nic is on its irq, and have replaced the network
cables with new, store-bought ones.
i'm stumped. as i mentioned before, tc or iptables is not bound to anything.
this is just straight-out-of-the-box bridging.
anyone out there had a simular problem? any advice?
i really appreciate your help.
thanks!!
matt
