Hi Han Zhou,
> If using localnet, it should rely on physical network (L2 and L3) to
reach the destination, not overlay, so adding the logical router here
doesn't make sense here
Why ovn have this limit for physical network? Does this mean that vlan
network can not use the l3 function of ovn?
Thanks

Here you have both logical router and localnet ports, which doesn't seems
to make sense. The 2 VMs are on different vlan, which are not supposed to
be able to communicate with localnet port. However, it reveals a bug
introduced by recursive local-datapath filling, which is fixed in [1].
Because of this bug, VM1 is talking to VM2 directly using net2's localnet
port which tags VLAN2 directly. It is also the reason why CT didn't work.
Please try the patch [1] to see if it fixes the problem (it will not use
localnet port but overlay tunnel to reach the destination).
Regarding your configuration itself, localnet is for physical/provider
network. If using localnet, it should rely on physical network (L2 and L3)
to reach the destination, not overlay, so adding the logical router here
doesn't make sense here. Since these 2 VMs are on different VLANs, the
expected way for them to communicate is through external routers that
connects these 2 VLANs.
Alternatively, if these 2 HVs are L3 connected, you can use overlay
logical router to connect the 2 logical switches, and then the localnet
ports should not be created.
