I have a big problem with the bridge.
My SW router should provide a single IP Interface to three vlans. Ens19.998 and Ens19.998.4090 do have the same outer vlan cos of our network scenario.
Means either a single or a double tagged frame will be received from the bridge.
This works as expected and the bridge is switching between these l2 networks (vlans).
root@ovn-test:/home/sff00009# brctl show
bridge name bridge id STP enabled interfaces
br_TB001 8000.42b99b1e1cc9 no ens19.998
ens19.998.4090
ens20.300
but the br_TB001 has also an IP interface and the isc dhcrelay is installed and configured to provide a bootp relay for br_TB001
I do see that the relay receive from ens19.998 and the answer (Reply) is forward into the bridge.
But the bridge obviously drops the frame.
Why?
bridge fdb shows the correct mac 00:19:92:c6:9d:b6 at ens19.998 only
00:19:92:c6:9d:b6 dev ens19.998 master br_TB001
42:b9:9b:1e:1c:c9 dev ens19.998 vlan 1 master br_TB001 permanent
42:b9:9b:1e:1c:c9 dev ens19.998 master br_TB001 permanent
33:33:00:00:00:01 dev br_TB001 self permanent
01:00:5e:00:00:01 dev br_TB001 self permanent
33:33:ff:1e:1c:c9 dev br_TB001 self permanent
01:00:5e:00:00:fc dev br_TB001 self permanent
33:33:00:01:00:03 dev br_TB001 self permanent
33:33:00:00:00:01 dev docker0 self permanent
If I delete the second interface from the bridge… everything works as expected.
Where is my fault ?
Thanks a lot
