Symptom
We would like to get the following scenario running, which seems to be prevented by a bug:
Site 1:
Interface port-channel10
switchport vlan mapping 100-3000 dotq-tunnel 512
switchport mode trunk
switchport trunk allowed vlan 50,51,52, 512
Site 2:
Interface port-channel10
switchport vlan mapping 100-3000 dotq-tunnel 512
switchport mode trunk
switchport trunk allowed vlan 50,51,52,512
- all VLANs are mapped to L2 VNIs
Currently the traffic is forwarded for VLANs, until command "system dot1q-tunnel transit" is added. This breaks the forwarding.
Conditions
Trunk with vlan mapping and multiple allowed vlans + "system dot1q-tunnel transit" command.
