Hi misc@,
I'm trying to bridge a VLAN between two routers with a vxlan(4) interface.
Setup:
router 1 (6.3):
physical interface (em) - vlan (with IP address) - bridge - vxlan
The two routers are connected directly, the traffic is encrypted with IPSec
and encapsulated in etherip(4), routed traffic is working perfectly.
router 2 (6.3-current):
vxlan - bridge - vlan (no IP address) - parent interface (sk0) -
switch - devices
With this configuration, the parent interface on router 2 (sk0) isn't in
promiscous mode and no traffic can pass into the vlan interface on router 2
(the devices attached to the switch receive echo requests and answer, but the
answer is not received on the vlan interface, only on the parent interface (sk0)
in encapsulated form).
Outgoing traffic can be seen on the vlan interface.
If I assign an IP address to the vlan device on router 2, the parent
interface (sk0)
flags change from:
sk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
to:
sk0: flags=8b43<UP,BROADCAST,RUNNING,PROMISC,ALLMULTI,SIMPLEX,MULTICAST>
mtu 1500
and traffic can flow over the vlan interface, it keeps working even
after deleting the
IP address (sk0 stays in promisc. mode).
Even when I delete the vlan interface after deleting the IP address
and add the vlan
interface again it keeps working until I reboot.
running tcpdump on sk0 or adding it to a bridge with no other members also makes
traffic flow and puts sk0 in promisc mode, but exiting
tcpdump/destroying the bridge
removes the PROMISC flag again.
Easiest way to reproduce this is creating a vlan interface on top of a
ethernet interface
with and without an IP address for the vlan interface. (also tried it
with an rl interface,
got the same behaviour).
disabling pf doesn't change anything.
Am I doing something wrong/is this behaviour intended or indeed a bug?
If you need any more information/want me to reproduce this with a simpler setup,
I'll be happy to help.
dmesg of router 2 is attached.
Thanks for any help!
Regards,
Sigi Rudzio
