Open Stack

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 at 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
