Guys, I have an "all-in-one" OpenStack Juno setup, with LinuxBridges, where I'm planning to use it with two tagged networks.
Like this: For "Instance #1", "brctl show" returns: ---- root@openstack-1:~# brctl show bridge name bridge id STP enabled interfaces brqfac384d5-cd 8000.ecf4bbd0417a no eth2.100 tap47417a6d-3b ---- For "Instance #2", "brctl show" returns: ---- bridge name bridge id STP enabled interfaces brq50721b16-1c 8000.ecf4bbd0417a no eth2.101 tap15f2960f-54 ---- "Instance #1" works as expected, I can see the the packets arriving inside the Instance attached to the TAP "tap15f2960f-54". Also, I can run "tcpdump -c 100 -eni tap15f2960f-54" or "tcpdump -c 100 -eni brq50721b16-1c" to see the packets. BUT, my second "Instance #2" doesn't receive the packets!! # "Wire" If I run "tcpdump -c 100 -eni eth2", I can see both "vlan 100" and "vlan 101" packets arriving. # vlan 100 - okay If I run "tcpdump -c 100 -eni brqfac384d5-cd", as I said before, I can see the packets. If I run "tcpdump -c 100 -eni tap47417a6d-3b", as I said before, I can see the packets. # vlan 101 - not okay If I run "tcpdump -c 100 -eni brq50721b16-1c", I can see the packets. If I run "tcpdump -c 100 -eni tap15f2960f-54", BOOM! I am unable to see the packets!! -- Why the packets are being dropped between "brq50721b16-1c" and "tap15f2960f-54" ??? "ifconfig tap15f2960f-54" shows packets being dropped. "ifconfig tap47417a6d-3b" shows 0 packets being dropped. I already double checked everything!! Also, I tried to raise txqueue, checked ebtabled, iptables... I have no clue about whats going on here... I really appreciate any help! Thanks! Thiago
